BL3894 Overview
BL389X series operates from a single 1.8V to 5.5V supply or dual ±0.9V to ±2.75V supplies，the amplifiers offer bandwidth of 1.8MHz, rail-to-rail inputs and outputs.The BL389X amplifier is micro-power, zero-drift CMOS operational amplifiers, BL389X uses chopper stabilized technique to provide very low offset voltage (less than 30µV maximum) and near zero drift over temperature. The BL389X offers excellent CMRR...
