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 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. With a typical offset voltage of only 10 µV, offset drift of 0.5 µV/°C, and noise of only 0.2 μV p-p (0.1 Hz to 10 Hz), they are perfectly suited for applications where large error sources cannot be tolerated. 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 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.
