description
The TLV2711 is a single low-voltage operational
amplifier available in the SOT-23 package. It
consumes only 11
µA
(typ) of supply current and
is ideal for battery-power applications. Looking at
Figure 1, the TLV2711 has a 3-V noise level of
21 nV/√Hz at 1 kHz; five times lower than
competitive SOT-23 micropower solutions. The
device exhibits rail-to-rail output performance for
increased dynamic range in single- or split-supply
applications. The TLV2711 is fully characterized
at 3 V and 5 V and is optimized for low-voltage
applications.
The TLV2711, exhibiting high input impedance
and low noise, is excellent for small-signal
conditioning for high-impedance sources, such as
piezoelectric transducers. Because of the micro-
power 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).

With a total area of 5.6mm

, 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.
