FEATURES
DESCRIPTION
● RAIL-TO-RAIL INPUT AND OUTPUT
The OPA703 and OPA704 series op amps are optimized for
applications requiring rail-to-rail input and output swing.
Single, dual, and quad versions are offered in a variety of
packages. While the quiescent current is less than 200µA per
amplifier, the OPA703 still offers excellent dynamic perfor-
mance (1MHz GBW and 0.6V/µs SR) and unity-gain stabil-
ity. The OPA704 is optimized for gains of 5 or greater and
provides 3MHz GBW and 3V/µs slew rate.
● WIDE SUPPLY RANGE:
Single Supply: 4V to 12V
Dual Supplies: ±2 to ±6
● LOW QUIESCENT CURRENT: 160µA
● FULL-SCALE CMRR: 90dB
● LOW OFFSET: 160µV
● HIGH SPEED:
The OPA703 and OPA704 series are fully specified and
guaranteed over the supply range of ±2V to ±6V. Input
swing extends 300mV beyond the rail and the output swings
to within 40mV of the rail.
OPA703: 1MHz, 0.6V/µs
OPA704: 3MHz, 3V/µs
● MicroSIZE PACKAGES:
SOT23-5, MSOP-8, TSSOP-14
The single versions (OPA703 and OPA704) are available in
the MicroSIZE SOT23-5 and in the standard SO-8 surface-
mount, as well as the DIP-8 packages. Dual versions
(OPA2703 and OPA2704) are available in the MSOP-8,
SO-8, and DIP-8 packages. The quad OPA4703 and
OPA4704 are available in the TSSOP-14 and SO-14 pack-
ages. All are specified for operation from –40°C to +85°C.
● LOW INPUT BIAS CURRENT: 1pA

This integrated circuit can be damaged by ESD. Texas Instru-
ments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
Output Short-Circuit(3) .............................................................. Continuous
Operating Temperature ..................................................–55°C to +125°C
Storage Temperature .....................................................–65°C to +150°C
Junction Temperature .................................................................... +150°C
Lead Temperature (soldering, 10s)............................................... +300°C
ESD damage can range from subtle performance degrada-
tion to complete device failure. Precision integrated circuits
may be more susceptible to damage because very small
parametric changes could cause the device not to meet its
published specifications.
NOTES: (1) Stresses above these ratings may cause permanent damage.
Exposure to absolute maximum conditions for extended periods may
degrade device reliability. (2) Input terminals are diode-clamped to the power
supply rails. Input signals that can swing more than 0.3V beyond the supply
rails should be current-limited to 10mA or less. (3) Short-circuit to ground,
one amplifier per package.

APPLICATIONS INFORMATION
OPA703 and OPA704 series op amps can operate on 160µA
quiescent current from a single (or split) supply in the range
of 4V to 12V (±2V to ±6V), making them highly versatile
and easy to use. The OPA703 is unity-gain stable and offers
1MHz bandwidth and 0.6V/µs slew rate. The OPA704 is
optimized for gains of 5 or greater with a 3MHz bandwidth
and 3V/µs slew rate.
OPERATING VOLTAGE
OPA703 and OPA704 series op amps are fully specified and
guaranteed from +4V to +12V over a temperature range of
–40ºC to +85ºC. Parameters that vary significantly with
operating voltages or temperature are shown in the Typical
Performance Curves.
Rail-to-rail input and output swing helps maintain dynamic
range, especially in low supply applications. Figure 1 shows
the input and output waveforms for the OPA703 in unity-
gain configuration. Operation is from a ±5V supply with a
100kΩ load connected to VS/2. The input is a 10Vp-p
sinusoid. Output voltage is approximately 10Vp-p.
RAIL-TO-RAIL INPUT
The input common-mode voltage range of the OPA703 series
extends 300mV beyond the supply rails at room temperature.
This is achieved with a complementary input stage—an N-
channel input differential pair in parallel with a P-channel
differential pair, as shown in Figure 2. The N-channel pair is
active for input voltages close to the positive rail, typically
(V+) – 2.0V to 300mV above the positive supply, while the P-
channel pair is on for inputs from 300mV below the negative
supply to approximately (V+) – 1.5V. There is a small
transition region, typically (V+) – 2.0V to (V+) – 1.5V, in
which both pairs are on. This 500mV transition region can
vary ±100mV with process variation. Thus, the transition
region (both stages on) can range from (V+) – 2.1V to (V+)
– 1.4V on the low end, up to (V+) – 1.9V to (V+) – 1.6V on
the high end. Within the 500mV transition region PSRR,
CMRR, offset voltage, and offset drift, and THD may vary
compared to operation outside this region.

INPUT VOLTAGE
CAPACITIVE LOAD AND STABILITY
The OPA703 and OPA704 series op amps can drive up to
1000pF pure capacitive load. Increasing the gain enhances
the amplifier’s ability to drive greater capacitive loads (see
the typical performance curve “Small Signal Overshoot vs
Capacitive Load”).
Device inputs are protected by ESD diodes that will conduct
if the input voltages exceed the power supplies by more than
approximately 300mV. Momentary voltages greater than
300mV beyond the power supply can be tolerated if the
current is limited to 10mA. This is easily accomplished with
an input resistor, as shown in Figure 3. Many input signals
are inherently current-limited to less than 10mA; therefore,
a limiting resistor is not always required. The OPA703
features no phase inversion when the inputs extend beyond
supplies if the input current is limited, as seen in Figure 4.
One method of improving capacitive load drive in the unity-
gain configuration is to insert a 10Ω to 20Ω resistor inside
the feedback loop, as shown in Figure 5. This reduces
ringing with large capacitive loads while maintaining DC
accuracy.

APPLICATION CIRCUITS
VS = ±5.0V, VIN = 11Vp-p
Figure 6 shows a G = 5 non-inverting amplifier implemented
with the OPA703 and OPA704 op amps. It demonstrates the
increased speed characteristics (bandwidth, slew rate and
settling time) that can be achieved with the OPA704 family
when used in gains of five or greater. Some optimization of
feedback capacitor value may be required to achieve best
dynamic response. Circuits with closed-loop gains of less
than five should use the OPA703 family for good stability
and capacitive load drive. The OPA703 can be used in gains
greater than five, but will not provide the increased speed
benefits of the OPA704 family.
20µs/div
The OPA703 series op amps are optimized for driving
medium-speed sampling data converters. The OPA703 op
amps buffer the converter’s input capacitance and resulting
charge injection while providing signal gain.
FIGURE 4. OPA703—No Phase Inversion with Inputs
Greater than the Power-Supply Voltage.
Figure 7 shows the OPA2703 in a dual-supply buffered
reference configuration for the DAC7644. The DAC7644 is
a 16-bit, low-power, quad-voltage output converter. Small
size makes the combination ideal for automatic test equip-
ment, data acquisition systems, and other low-power space-
limited applications.
RAIL-TO-RAIL OUTPUT
A class AB output stage with common-source transistors is
used to achieve rail-to-rail output. This output stage is
capable of driving 1kΩ loads connected to any point be-
tween V+ and ground. For light resistive loads (> 100kΩ),
the output voltage can swing to 40mV from the supply rail.
With moderate resistive loads (20kΩ), the output can swing
to within 75mV from the supply rails while maintaining high
open-loop gain (see the typical performance curve “Output
Voltage Swing vs Output Current”).

(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.
