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.
