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 family of devices, 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
The TLC227x also make great upgrades to the TLC27x 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, TLV2221 and TLV2231 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.
