HT92112/HT92122
Low Power OPAMP
General Description
The HT92112/HT92122 family of low power op-
erational amplifiers offers the benefits of low power
consumption, low offset voltage and low offset drift.
They have low 1/f noise and have good PSRR and
CMRR characteristics. The devices also provide full
rail-to-rail input and output operation. The HT92112
has a gain bandwidth product of 14kHz while the
HT92122 has a gain bandwidth product of 100kHz.
These devices operate with a single supply volt-
age as low as 1.4V and with a low supply current of
1μA/amplifier (Max.). These low power operational
amplifiers can be implemented in a wide range of
applications for portable devices and battery powered
equipment.
With their single supply operation and low power
consumption features coupled with their low offset
voltage these operational amplifiers are suitable for
use in a wide range of applications. With regard to
packaging, both devices are supplied in 8-pin SOP/
MSOP package formats.
