GENERAL DESCRIPTION AD8624ARUZ

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.
