description
The TLV2731 is a single low-voltage operational amplifier available in the SOT-23 package. It offers 2 MHz of
bandwidth and 1.6 V/µs of slew rate for applications requiring good ac performance. The device exhibits
rail-to-rail output performance for increased dynamic range in single or split supply applications. The TLV2731
is fully characterized at 3 V and 5 V and is optimized for low-voltage applications.
The TLV2731, exhibiting high input impedance and low noise, is excellent for small-signal conditioning of
high-impedance sources, such as piezoelectric transducers. Because of the micropower dissipation levels
combined with 3-V operation, these devices work well in hand-held monitoring and remote-sensing
applications. In addition, the rail-to-rail output feature with single- or split-supplies makes this family a great
choice when interfacing with analog-to-digital converters (ADCs). The device can also drive 600-Ω loads for
telecom applications.
With a total area of 5.6mm2, the SOT-23 package only requires one-third the board space of the standard 8-pin
SOIC package. This ultra-small package allows designers to place single amplifiers very close to the signal
source, minimizing noise pick-up from long PCB traces.

† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltage values, except differential voltages, are with respect to VDD – .
2. Differential voltages are at the noninverting input with respect to the inverting input. Excessive current flows when input is brought
below VDD – – 0.3 V.
3. The output may be shorted to either supply. Temperature and /or supply voltages must be limited to ensure that the maximum
dissipation rating is not exceeded.

APPLICATION INFORMATION
driving large capacitive loads
The TLV2731 is designed to drive larger capacitive loads than most CMOS operational amplifiers. Figure 49
through Figure 54 illustrate its ability to drive loads greater than 100 pF while maintaining good gain and phase
margins (Rnull = 0).
A small series resistor (Rnull) at the output of the device (see Figure 55) improves the gain and phase margins
when driving large capacitive loads. Figure 49 through Figure 52 show the effects of adding series resistances
of 50 Ω, 100 Ω, 500 Ω, and 1000 Ω. The addition of this series resistor has two effects: the first effect is that
it adds a zero to the transfer function and the second effect is that it reduces the frequency of the pole associated
with the output load in the transfer function.
The zero introduced to the transfer function is equal to the series resistance times the load capacitance. To
calculate the approximate improvement in phase margin, equation 1 can be used.
ǒ
Ǔ
+ tan–1 2 × π × UGBW × Rnull × CL
Where :
∆φ m1 + Improvement in phase margin
UGBW + Unity-gain bandwidth frequency
R null + Output series resistance
C L + Load capacitance
∆φ m1
(1)
The unity-gain bandwidth (UGBW) frequency decreases as the capacitive load increases (see Figure 53 and
Figure 54). To use equation 1, UGBW must be approximated from Figure 53 and Figure 54.

macromodel information
Macromodel information provided was derived using Microsim Parts, the model generation software used
with Microsim PSpice . The Boyle macromodel (see Note 6) and subcircuit in Figure 56 are generated using
the TLV2731 typical electrical and operating characteristics at TA = 25°C. Using this information, output
simulations of the following key parameters can be generated to a tolerance of 20% (in most cases):
