description

The TLC2252 and TLC2254 are dual and

quadruple operational amplifiers from Texas

Instruments. Both devices exhibit rail-to-rail

output performance for increased dynamic range

in single- or split-supply applications. The

TLC225x family consumes only 35

µA of supply

current per channel. This micropower operation

makes them good choices for battery-powered

applications. The noise performance has been

dramatically improved over previous generations

of CMOS amplifiers. Looking at Figure 1, the

TLC225x has a noise level of 19 nV/

√Hz at 1kHz;

four times lower than competitive micropower

solutions.

The TLC225x amplifiers, 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,

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 TLC225xA family is available and has a maximum input offset voltage of 850

µV. This

family is fully characterized at 5 V and

±5 V.
