GS8334/SOP14/TSSOP14
General Description
The GS833X amplifier is single/dual/quad 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 1.8V 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 25µA 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 GS8334 Quad is available in Green SOP-14 and TSSOP-14 packages. The extended temperature range of
-45oC to +125oC over all supply voltages offers additional d
