description

The TLV2211 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 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).
