GENERAL DESCRIPTION

noise combined with very low input bias currents over the full operating

temperature range. Operation is fully specified from ±± V to ±ꢀ± V.

The AD8622 is a dual low power (330 μA max over temperature and

supply), precision, rail-to-rail operational amplifiers.

With typical offset voltage of only ꢀ0 ꢁV, offset drift of 0.2 ꢁV/°C, and noise

of only TBD μV p-p (0.ꢀ Hz to ꢀ0 Hz), these is perfectly suited for

applications where large error sources cannot be tolerated. Many systems

can take advantage of the low bias current, low noise, dc precision, and rail-

to-rail output swing provided by the devices to maximize SNR and dynamic

range for low power operation.

The AD8622 is designed on ADI’s iPOLAR^TMprocess implementing bias

cancellation circuits to guarantee low bias current over temperature. ADI’s

proprietary iPolar process is an advanced bipolar technology implementing

vertical junction isolation with lateral trench isolation, allowing for low

noise performance amplifiers in smaller die size at faster speed and lower

power. These operational amplifiers offer ultralow offset, drift, and voltage
