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 5.6mm2, 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.
