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.
