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 rail-
to-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.
