The HT92112/HT92122 family of low power operational 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 voltage 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 package formats.
