GENERAL DESCRIPTION
The AD8622/AD8624 are dual and quad precision rail-to-rail output operational amplifiers with low supply currents of only 350 µA/amplifier maximum over temperature and supply voltages. The AD8622/AD8624 also has an input bias current cancellation circuitry that provides a very low input bias current over the full operating temperature.

FEATURES
    Very low offset voltage 125 μV maximum
    Supply current: 215 μA/amp typical
    Input bias current: 200 pA maximum
    Low input offset voltage drift: 1.2 μV/°C maximum
    Very low voltage noise: 11 nV/√Hz
    Operating temperature: −40°C to +125°C
    Rail-to-rail output swing
    Unity gain stable
    ±2.5 V to ±15 V operation

APPLICATIONS
    Portable precision instrumentation
    Laser diode control loops
    Strain gage amplifiers
    Medical instrumentation
    Thermocouple amplifiers
