description

The TLC2272A and TLC2274A 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

TLC227xA family offers 2 MHz of bandwidth and

3 V/μs of slew rate for higher speed applications.

These devices offer comparable ac performance

while having better noise, input offset voltage, and

power dissipation than existing CMOS

operational amplifiers. The TLC227xA has a noise

voltage of 9 nV/√Hz, two times lower than

competitive solutions.

The TLC227xA, exhibiting high input impedance

and low noise, is 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

TLC227xA family has a maximum input offset voltage of 950 μV. This family is fully characterized at 5 V and

±5 V.

The TLC2272/4 also makes great upgrades to the TLC272/4 or TS272/4 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.
