General Description

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 without the crossover associated with traditional complementary input stages.

The BL3891 is available in SOT23-5 and SOP-8 packages.
