3 Description

The TLC2274 is a quadruple operational amplifier

from Texas Instruments. The device exhibits rail-to- rail output performance for increased dynamic range

in single- or split-supply applications. The TLC2274

offers 2 MHz of bandwidth and 3 V/μs of slew rate for

higher speed applications. These device offers comparable ac performance while having better

noise, input offset voltage, and power dissipation than

existing CMOS operational amplifiers. The TLC2274

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

competitive solutions.

The TLC2274, 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, this device works well in hand-held monitoring

and remote-sensing applications. In addition, the railto-

rail output feature, with single- or split-supplies,

makes this device a great choice when interfacing

with analog-to-digital converters (ADCs). This family is fully characterized at 5 V and ±5 V.

It offers increased output dynamic range, lower noise

voltage, and lower input offset voltage. This

enhanced feature set allows the device to be used in

a wider range of applications.
