DESCRIPTION
The TLC2272 and TLC2274 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 TLC227x 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 TLC227x has a noise
voltage of 9 nV/√Hz, two times lower than competitive
solutions.
The TLC227x, 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 is
available with 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. For applications that require higher
output drive and wider input voltage range, see the
TLV2432 and TLV2442 devices.
