AD8622

The AD8622 is available in lead-free 8-lead SOIC and MSOP packages, while the AD8624 is available in lead-free 14-lead TSSOP and 16-lead LFCSP packages. The AD8622/AD8624 are dual and quad precision rail-to-rail output operational amplifiers with low supply currents of only 350 A/amplifier maximum over temperature and supply voltages. Many systems can take advantage of the low noise, dc precision, and rail-to-rail output swing provided by the AD8622/AD8624 to maximize the signal-to-noise ratio and dynamic range for low power operation. The AD8622/ AD8624 are specified for the extended industrial temperature range of -40°C to +125°C. The AD8622/AD8624 also has an input bias current cancellation circuitry that provides a very low input bias current over the full operating temperature. With a typical offset voltage of only 10 V, offset drift of 0.5 V/°C, and noise of only 0.2 V p-p (0.1 Hz to 10 Hz), they are perfectly suited for applications where large error sources cannot be tolerated.

The features of AD8622 can be summarized as (1)very low offset voltage 125 V maximum; (2)supply current: 215 A/amp typical; (3)input bias current: 200 pA maximum; (4)low input offset voltage drift: 1.2 V/°C maximum; (5)very low voltage noise: 11 nV/Hz; (6)operating temperature: -40°C to +125°C; (7)rail-to-rail output swing; (8)unity gain stable; (9)±2.5 V to ±15 V operation.

The absolute maximum ratings of AD8622 are (1)supply voltage: ±18 V; (2)input voltage: ±V SY; (3)input current: ±10 mA; (4)differential input voltage: 2 ±10 V; (5)output short-circuit duration to GND: indefinite; (6)storage temperature range: -65°C to +150°C; (7)operating temperature range: -40°C to +125°C; (8)junction temperature range: -65°C to +150°C; (9)lead temperature (soldering, 60 sec): 300°C.
