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 TLV2211 has a 3-V noise level of
22 nV/√Hz at 1kHz; 5 times lower than competitive
SOT-23 micropower solutions. The device
exhibits rail-to-rail output performance for in-
creased dynamic range in single- or split-supply
applications. The TLV2211 is fully characterized
at 3 V and 5 V and is optimized for low-voltage
applications.

The TLV2211, 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).
