ADA4051-1 - Rail-to-Rail I/O Amplifier

General Description

The ADA4051-1/ADA4051-2 are CMOS, micropower, zerodrift operational amplifiers utilizing an innovative chopping technique.

These amplifiers feature rail-to-rail input/output swing and extremely low offset voltage while operating from a 1.8 V to 5.5 V power supply.

Key Features

  • Very low supply current: 13 μA typical Low offset voltage: 15 μV maximum Offset voltage drift: 20 nV/°C Single-supply operation: 1.8 V to 5.5 V High PSRR: 110 dB minimum High CMRR: 110 dB minimum Rail-to-rail input/output Unity-gain stable Extended industrial temperature range.
