Overview
The AD8622ARZ-REEL is a dual precision operational amplifier manufactured by Analog Devices Inc. It features rail-to-rail output swing, low supply current of 215 µA per amplifier, and an input bias current cancellation circuit. The device operates within a supply voltage range of ±2.5 V to ±15 V and supports an extended industrial temperature range from -40°C to +125°C. Key electrical specifications include a maximum offset voltage of 125 µV, a typical offset drift of 0.5 µV/°C, and a gain bandwidth product of 560 kHz at ±15 V operation.
Feature Summary
- Features input bias current cancellation circuitry for very low input bias current across the full operating temperature range.
- Provides rail-to-rail output swing capability to maximize signal-to-noise ratio and dynamic range.
- Designed with internal protection diodes and series resistors to limit differential input voltage and prevent base-emitter junction breakdown.
Applications
- Portable precision instrumentation
- Laser diode control loops
- Strain gage amplifiers
- Medical instrumentation
- Thermocouple amplifiers
