General Description

The EC5731 amplifier is single supply, micro-power, zerodrift CMOS operational amplifier, the amplifier offer
bandwidth of 350kHz, rail-to-rail inputs and outputs, and single-supply operation from 2.2V to 5.5V.

EC5731 uses chopper stabilized technique to provide very low offset voltage (less than 20µV maximum) and near zero drift over temperature.

Low quiescent supply current of 20μA and very low input bias current of 10pA make the devices an ideal choice for low offset, low power consumption and high impedance applications.

The single EC5731 is available in space-saving, SOT23-5 and SOP-8 package.

The extended temperature range of -40℃ to +125℃ over all supply voltages offers additional design flexibility.
