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 micro-
power 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.
If the design requires single amplifiers, see the TLV2211/21/31 family. These devices are single rail-to-rail
operational amplifiers in the SOT-23 package. Their small size and low power consumption, make them ideal
for high density, battery-powered equipment.
