LMC6442 Dual Micropower Rail-to-Rail Output Single Supply Operational Amplifier
Check for Samples: LMC6442

FEATURES
DESCRIPTION
The LMC6442 is ideal for battery powered systems,
where very low supply current (less than one
microamp per amplifier) and Rail-to-Rail output swing
is required. It is characterized for 2.2V to 10V
operation, and at 2.2V supply, the LMC6442 is ideal
for single (Li-Ion) or two cell (NiCad or alkaline)
battery systems.

High Voltage Gain 103 dB

Low Supply Current 0.95 µA/Amplifier
Input Voltage Range −0.3V to V+ -0.9V
2.1 µW/Amplifier Power Consumption
Stable for AV ≥ +2 or AV ≤ −1
The LMC6442 is designed for battery powered
systems that require long service life through low
supply current, such as smoke and gas detectors,
and pager or personal communications systems.
Operation from single supply is enhanced by the wide
common mode input voltage range which includes the
ground (or negative supply) for ground sensing
applications. Very low (5 fA, typical) input bias current
and near constant supply current over supply voltage
enhance the LMC6442's performance near the end-
of-life battery voltage.

Designed for closed loop gains of greater than plus
two (or minus one), the amplifier has typically 9.5
KHz GBWP (Gain Bandwidth Product). Unity gain can
be used with a simple compensation circuit, which
also allows capacitive loads of up to 300 pF to be
driven, as described in the Application Information
section.

APPLICATIONS INFORMATION
USING LMC6442 IN UNITY GAIN APPLICATIONS
LMC6442 is optimized for maximum bandwidth and minimal external components when operating at a minimum
closed loop gain of +2 (or −1). However, it is also possible to operate the device in a unity gain configuration by
adding external compensation as shown in Figure 35:
Figure 35. AV = +1 Operation by adding CC and RC
Using this compensation technique it is possible to drive capacitive loads of up to 300 pF without causing
oscillations (see the Typical Performance Characteristics for step response plots). This compensation can also
be used with other gain settings in order to improve stability, especially when driving capacitive loads (for
optimum performance, RC and CC may need to be adjusted).
USING “T” NETWORK
Compromises need to be made whenever high gain inverting stages need to achieve a high input impedance as
well. This is especially important in low current applications which tend to deal with high resistance values. Using
a traditional inverting amplifier, gain is inversely proportional to the resistor value tied between the inverting
terminal and input while the input impedance is equal to this value. For example, in order to build an inverting
amplifier with an input impedance of 10MΩ and a gain of 100, one needs to come up with a feedback resistor of
1000 MΩ -an expensive task.
An alternate solution is to use a “T” Network in the feedback path, as shown in Figure 36.
Closed loop gain, AV is given by:
(1)
Figure 36. “T” Network Used to Replace High Value Resistor
It must be noted, however, that using this scheme, the realizable bandwidth would be less than the theoretical
maximum. With feedback factor, β, defined as:
(2)
BW(−3 dB) ≈ GBWP • β
(3)
In this case, assuming a GBWP of about 10 KHz, the expected BW would be around 50 Hz (vs. 100 Hz with the
conventional inverting amplifier).

Looking at the problem from a different view, with RF defined by AV•Rin, one could select a value for R in the “T”
Network and then determine R1 based on this selection:
(4)
Figure 37. “T” Network Values for Various Values of R
For convenience, Figure 37 shows R1 vs. RF for different values of R.
DESIGN CONSIDERATIONS FOR CAPACITIVE LOADS
As with many other opamps, the LMC6442 is more stable at higher closed loop gains when driving a capacitive
load. Figure 38 shows minimum closed loop gain versus load capacitance, to achieve less than 10% overshoot in
the output small signal response. In addition, the LMC6442 is more stable when it provides more output current
to the load and when its output voltage does not swing close to V−.
The LMC6442 is more tolerant to capacitive loads when the equivalent output load resistance is lowered or when
output voltage is 1V or greater from the V− supply. The capacitive load drive capability is also improved by
adding an isolating resistor in series with the load and the output of the device. Figure 39 shows the value of this
resistor for various capacitive loads (AV = −1), while limiting the output to less than 10 % overshoot.
Referring to the Typical Performance Characteristics plot of Phase Margin (Worst Case) vs. Supply Voltage, note
that Phase Margin increases as the equivalent output load resistance is lowered. This plot shows the expected
Phase Margin when the device output is very close to V−, which is the least stable condition of operation.
Comparing this Phase Margin value to the one read off the Open Loop Gain/Phase vs. Frequency plot, one can
predict the improvement in Phase Margin if the output does not swing close to V−. This dependence of Phase
Margin on output voltage is minimized as long as the output load, RL, is about 1MΩ or less.
Output Phase Reversal: The LMC6442 is immune against this behavior even when the input voltages exceed
the common mode voltage range.
Output Time Delay: Due to the ultra low power consumption of the device, there could be as long as 2.5 ms of
time delay from when power is applied to when the device output reaches its final value.

(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) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based
flame retardants must also meet the <=1000ppm threshold requirement.
(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5) Multiple Device Markings will be inside parentheses. Only one Device 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 Device Marking for that device.
(6)
Lead finish/Ball material - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two
lines if the finish value exceeds the maximum column width.
