General Description
The GS833X amplifier is single/dual supply, micro-power, zero-drift CMOS operational amplifiers, the amplifiers offer bandwidth
of 350 kHz, rail-to-rail inputs and outputs, and single-supply operation from 2.1V to 5.5V. GS833X uses chopper stabilized
technique to provide very low offset voltage (less than 10µV maximum) and near zero drift over temperature. Low quiescent
supply current of 20µA per amplifier and very low input bias current of 20pA make the devices an ideal choice for low offset, low
power consumption and high impedance applications. The GS833X offers excellent CMRR without the crossover associated
with traditional complementary input stages. This design results in superior performance for driving analog-to-digital
converters (ADCs) without degradation of differential linearity.
The GS8331 is available in SOT23-5 and SOP8 packages. And the GS8332 is available inMSOP8, SOP8 and DFN-8 packages. The extended temperature range of -40oC to +125oC over all supply voltages offers additional design flexibility.
