FEATURES
DESCRIPTION
The LMV358-N/LMV324-N are low voltage (2.7V to
5.5V) versions of the dual and quad commodity op
amps LM358/LM324 (5V to 30V). The LMV321-N is
the single channel version. The LMV321-N/LMV358-
N/LMV324-N are the most cost effective solutions for
applications where low voltage operation, space
efficiency, and low price are important. They offer
specifications that meet or exceed the familiar
LM358/LM324. The LMV321-N/LMV358-N/LMV324-N
have rail-to-rail output swing capability and the input
common-mode voltage range includes ground. They
all exhibit excellent speed to power ratio, achieving 1
MHz of bandwidth and 1 V/µs slew rate with low
supply current.

The LMV321-N is available in the space saving 5-Pin
SC70, which is approximately half the size of the 5-
Pin SOT23. The small package saves space on PC
boards and enables the design of small portable
electronic devices. It also allows the designer to place
the device closer to the signal source to reduce noise
pickup and increase signal integrity.

APPLICATION INFORMATION
BENEFITS OF THE LMV321-N/LMV358-N/LMV324-N
Size
The small footprints of the LMV321-N/LMV358-N/LMV324-N packages save space on printed circuit boards, and
enable the design of smaller electronic products, such as cellular phones, pagers, or other portable systems. The
low profile of the LMV321-N/LMV358-N/LMV324-N make them possible to use in PCMCIA type III cards.
Signal Integrity
Signals can pick up noise between the signal source and the amplifier. By using a physically smaller amplifier
package, the LMV321-N/LMV358-N/LMV324-N can be placed closer to the signal source, reducing noise pickup
and increasing signal integrity.
Simplified Board Layout
These products help you to avoid using long PC traces in your PC board layout. This means that no additional
components, such as capacitors and resistors, are needed to filter out the unwanted signals due to the
interference between the long PC traces.
Low Supply Current
These devices will help you to maximize battery life. They are ideal for battery powered systems.
Low Supply Voltage
Texas Instruments provides guaranteed performance at 2.7V and 5V. These guarantees ensure operation
throughout the battery lifetime.
Rail-to-Rail Output
Rail-to-rail output swing provides maximum possible dynamic range at the output. This is particularly important
when operating on low supply voltages.
Input Includes Ground
Allows direct sensing near GND in single supply operation.
Protection should be provided to prevent the input voltages from going negative more than −0.3V (at 25°C). An
input clamp diode with a resistor to the IC input terminal can be used.
Ease of Use and Crossover Distortion
The LMV321-N/LMV358-N/LMV324-N offer specifications similar to the familiar LM324-N. In addition, the new
LMV321-N/LMV358-N/LMV324-N effectively eliminate the output crossover distortion. The scope photos in
Figure 49 and Figure 50 compare the output swing of the LMV324-N and the LM324-N in a voltage follower
configuration, with VS = ± 2.5V and RL (= 2 kΩ) connected to GND. It is apparent that the crossover distortion
has been eliminated in the new LMV324-N.

CAPACITIVE LOAD TOLERANCE
The LMV321-N/LMV358-N/LMV324-N can directly drive 200 pF in unity-gain without oscillation. The unity-gain
follower is the most sensitive configuration to capacitive loading. Direct capacitive loading reduces the phase
margin of amplifiers. The combination of the amplifier's output impedance and the capacitive load induces phase
lag. This results in either an underdamped pulse response or oscillation. To drive a heavier capacitive load, the
circuit in Figure 51 can be used.
Figure 51. Indirectly Driving a Capacitive Load Using Resistive Isolation
In Figure 51 , the isolation resistor RISO and the load capacitor CL form a pole to increase stability by adding more
phase margin to the overall system. The desired performance depends on the value of RISO. The bigger the RISO
resistor value, the more stable VOUT will be. Figure 52 is an output waveform of Figure 51 using 620Ω for RISO
and 510 pF for CL..
Figure 52. Pulse Response of the LMV324 Circuit in Figure 51
The circuit in Figure 53 is an improvement to the one in Figure 51 because it provides DC accuracy as well as
AC stability. If there were a load resistor in Figure 51, the output would be voltage divided by RISO and the load
resistor. Instead, in Figure 53, RF provides the DC accuracy by using feed-forward techniques to connect VIN to
RL. Caution is needed in choosing the value of RF due to the input bias current of theLMV321-N/LMV358-
N/LMV324-N. CF and RISO serve to counteract the loss of phase margin by feeding the high frequency
component of the output signal back to the amplifier's inverting input, thereby preserving phase margin in the
overall feedback loop. Increased capacitive drive is possible by increasing the value of CF . This in turn will slow
down the pulse response.

INPUT BIAS CURRENT CANCELLATION
The LMV321-N/LMV358-N/LMV324-N family has a bipolar input stage. The typical input bias current of LMV321-
N/LMV358-N/LMV324-N is 15 nA with 5V supply. Thus a 100 kΩ input resistor will cause 1.5 mV of error voltage.
By balancing the resistor values at both inverting and non-inverting inputs, the error caused by the amplifier's
input bias current will be reduced. The circuit in Figure 54 shows how to cancel the error caused by input bias
current.

TYPICAL SINGLE-SUPPLY APPLICATION CIRCUITS
Difference Amplifier
The difference amplifier allows the subtraction of two voltages or, as a special case, the cancellation of a signal
common to two inputs. It is useful as a computational amplifier, in making a differential to single-ended
conversion or in rejecting a common mode signal.

Figure 55. Difference Amplifier
Instrumentation Circuits
The input impedance of the previous difference amplifier is set by the resistors R1, R2, R3, and R4. To eliminate
the problems of low input impedance, one way is to use a voltage follower ahead of each input as shown in the
following two instrumentation amplifiers.
Three-Op-Amp Instrumentation Amplifier
The quad LMV324 can be used to build a three-op-amp instrumentation amplifier as shown in Figure 56.
Figure 56. Three-Op-Amp Instrumentation Amplifier
The first stage of this instrumentation amplifier is a differential-input, differential-output amplifier, with two voltage
followers. These two voltage followers assure that the input impedance is over 100 MΩ. The gain of this
instrumentation amplifier is set by the ratio of R2/R1. R3 should equal R1, and R4 equal R2. Matching of R3 to R1
and R4 to R2 affects the CMRR. For good CMRR over temperature, low drift resistors should be used. Making R4
slightly smaller than R2 and adding a trim pot equal to twice the difference between R2 and R4 will allow the
CMRR to be adjusted for optimum performance.
Two-Op-Amp Instrumentation Amplifier
A two-op-amp instrumentation amplifier can also be used to make a high-input-impedance DC differential
amplifier (Figure 57). As in the three-op-amp circuit, this instrumentation amplifier requires precise resistor
matching for good CMRR. R4 should equal R1 and, R3 should equal R2.

Figure 57. Two-Op-Amp Instrumentation Amplifier
Single-Supply Inverting Amplifier
There may be cases where the input signal going into the amplifier is negative. Because the amplifier is
operating in single supply voltage, a voltage divider using R3 and R4 is implemented to bias the amplifier so the
input signal is within the input common-mode voltage range of the amplifier. The capacitor C1 is placed between
the inverting input and resistor R1 to block the DC signal going into the AC signal source, VIN. The values of R1
and C1 affect the cutoff frequency, fc = 1/2πR1C1.
As a result, the output signal is centered around mid-supply (if the voltage divider provides V+/2 at the non-
inverting input). The output can swing to both rails, maximizing the signal-to-noise ratio in a low voltage system.

ACTIVE FILTER
Simple Low-Pass Active Filter
The simple low-pass filter is shown in Figure 59. Its low-frequency gain (ω → 0) is defined by −R3/R1. This allows
low-frequency gains other than unity to be obtained. The filter has a −20 dB/decade roll-off after its corner
frequency fc. R2 should be chosen equal to the parallel combination of R1 and R3 to minimize errors due to bias
current. The frequency response of the filter is shown in Figure 60.

Note that the single-op-amp active filters are used in the applications that require low quality factor, Q( ≤ 10), low
frequency (≤ 5 kHz), and low gain (≤ 10), or a small value for the product of gain times Q (≤ 100). The op amp
should have an open loop voltage gain at the highest frequency of interest at least 50 times larger than the gain
of the filter at this frequency. In addition, the selected op amp should have a slew rate that meets the following
requirement:
Slew Rate ≥ 0.5 × (ω HVOPP) × 10−6 V/µsec

where ωH is the highest frequency of interest, and VOPP is the output peak-to-peak voltage.

The above resistor values are normalized values with ωn = 1 rad/s and C1 = C2 = Cn = 1F. To scale the
normalized cutoff frequency and resistances to the real values, two scaling factors are introduced, frequency
scaling factor (kf) and impedance scaling factor (km).

Scaled values:
R2 = R1 = 15.9 kΩ
R3 = R4 = 63.6 kΩ
C1 = C2 = 0.01 µF

An adjustment to the scaling may be made in order to have realistic values for resistors and capacitors. The
actual value used for each component is shown in the circuit.
2nd-Order High Pass Filter
A 2nd-order high pass filter can be built by simply interchanging those frequency selective components (R1, R2,
C1, C2) in the Sallen-Key 2nd-order active low pass filter. As shown in Figure 62, resistors become capacitors,
and capacitors become resistors. The resulted high pass filter has the same corner frequency and the same
maximum gain as the previous 2nd-order low pass filter if the same components are chosen.

A state variable filter requires three op amps. One convenient way to build state variable filters is with a quad op
amp, such as the LMV324 (Figure 63).
This circuit can simultaneously represent a low-pass filter, high-pass filter, and bandpass filter at three different
outputs. The equations for these functions are listed below. It is also called "Bi-Quad" active filter as it can
produce a transfer function which is quadratic in both numerator and denominator.

PULSE GENERATORS AND OSCILLATORS
A pulse generator is shown in Figure 64. Two diodes have been used to separate the charge and discharge
paths to capacitor C.
Figure 64. Pulse Generator
When the output voltage VO is first at its high, VOH, the capacitor C is charged toward VOH through R2. The
voltage across C rises exponentially with a time constant τ = R2C, and this voltage is applied to the inverting
input of the op amp. Meanwhile, the voltage at the non-inverting input is set at the positive threshold voltage
(VTH+) of the generator. The capacitor voltage continually increases until it reaches VTH+, at which point the
output of the generator will switch to its low, VOL which 0V is in this case. The voltage at the non-inverting input is
switched to the negative threshold voltage (VTH−) of the generator. The capacitor then starts to discharge toward
VOL exponentially through R1, with a time constant τ = R1C. When the capacitor voltage reaches VTH−, the output
of the pulse generator switches to VOH. The capacitor starts to charge, and the cycle repeats itself.

CURRENT SOURCE AND SINK
The LMV321-N/LMV358-N/LMV324-N can be used in feedback loops which regulate the current in external PNP
transistors to provide current sources or in external NPN transistors to provide current sinks.
Fixed Current Source
A multiple fixed current source is shown in Figure 68. A voltage (VREF = 2V) is established across resistor R3 by
the voltage divider (R3 and R4). Negative feedback is used to cause the voltage drop across R1 to be equal to
VREF. This controls the emitter current of transistor Q1 and if we neglect the base current of Q1 and Q2,
essentially this same current is available out of the collector of Q1.
Large input resistors can be used to reduce current loss and a Darlington connection can be used to reduce
errors due to the β of Q1.
The resistor, R2, can be used to scale the collector current of Q2 either above or below the 1 mA reference value.

COMPARATOR WITH HYSTERESIS
The LMV321-N/LMV358-N/LMV324-N can be used as a low power comparator. Figure 72 shows a comparator
with hysteresis. The hysteresis is determined by the ratio of the two resistors.
VTH+ = VREF/(1+R 1/R2)+VOH/(1+R2/R1)
VTH− = VREF/(1+R 1/R2)+VOL/(1+R2/R1)
VH = (VOH−VOL)/(1+R 2/R1)
(30)
(31)
(32)
where
VTH+: Positive Threshold Voltage
VTH−: Negative Threshold Voltage
VOH: Output Voltage at High
VOL: Output Voltage at Low
VH: Hysteresis Voltage
Since LMV321-N/LMV358-N/LMV324-N have rail-to-rail output, the (VOH−VOL) is equal to VS, which is the supply
voltage.
VH = VS/(1+R2/R1)
(33)
The differential voltage at the input of the op amp should not exceed the specified absolute maximum ratings.
For real comparators that are much faster, we recommend you use Texas Instruments's
LMV331/LMV93/LMV339, which are single, dual and quad general purpose comparators for low voltage
operation.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
(3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
(4)
Multiple Top-Side Markings will be inside parentheses. Only one Top-Side Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a
continuation of the previous line and the two combined represent the entire Top-Side Marking for that device.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
