description

The TLV2252 and TLV2254 are dual and

quadruple low-voltage operational amplifiers from

Texas Instruments. Both devices exhibit rail-to-rail

output performance for increased dynamic range

in single- or split-supply applications. The

TLV225x family consumes only 34 μA of supply

current per channel. This micropower operation

makes them good choices for battery-powered

applications. This family is fully characterized at

3 V and 5 V and is optimized for low-voltage

applications. The noise performance has been

dramatically improved over previous generations

of CMOS amplifiers. The TLV225x has a noise

level of 19 nV/√Hz at 1kHz, four times lower than

competitive micropower solutions.

The TLV225x, exhibiting high input impedance

and low noise, are excellent for small-signal

conditioning for 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). For precision

applications, the TLV225xA family is available and has a maximum input offset voltage of 850 μV.

The TLV2252/4 also make great upgrades to the TLV2322/4 in standard designs. They offer increased output

dynamic range, lower noise voltage, and lower input offset voltage. This enhanced feature set allows them to

be used in a wider range of applications. For applications that require higher output drive and wider input voltage

range, see the TLV2432 and TLV2442 devices. If your design requires single amplifiers, please see the

TLV2211/21/31 family. These devices are single rail-to-rail operational amplifiers in the SOT-23 package. Their

small size and low power consumption, make them ideal for high density, battery-powered equipment.
