GS8331/8332 350KHZ Zero-Drift CMOS Rail-to-Rail IO Opamp with RFFilter
The GS833X amplifier is single/dual supply, micro-power,zero-drift CMOS operational amplifiers, the amplifiers offerbandwidth of 350 kHz, rail-to-rail inputs and outputs, andsingle-supply operation from 1.8V to 5.5V. GS833X uses chopperstabilized technique to provide very low offset voltage (less than10µV maximum) and near zero drift over temperature. Low quiescentsupply current of 25µA per amplifier and very low input biascurrent of 20pA make the devices an ideal choice for low offset,low power consumption and high impedance applications. The GS833Xoffers excellent CMRR without the crossover associated withtraditional complementary input stages. This design results insuperior performance for driving analog-to-digital converters(ADCs) without degradation of differential linearity.
