AD8628 - Rail-to-Rail Input/Output Operational Amplifier

Datasheet Summary

Description

This amplifier has ultralow offset, drift, and bias current.

The AD8628/AD8629/AD8630 are wide bandwidth auto-zero amplifiers featuring rail-to-rail input and output swing and low noise.

Operation is fully specified from 2.7 V to 5 V single supply (±1.35 V to ±2.5 V dual supply).

Features

  • Lowest auto-zero amplifier noise.
  • Low offset voltage: 1 µV.
  • Input offset drift: 0.002 µV/°C.
  • Rail-to-rail input and output swing.
  • 5 V single-supply operation.
  • High gain, CMRR, and PSRR: 130 dB.
  • Very low input bias current: 100 pA maximum.
  • Low supply current: 1.0 mA.
  • Overload recovery time: 50 µs.
  • No external components required.
  • Qualified for automotive.
