GENERAL DESCRIPTION
The AD8622 is a dual, precision rail-to-rail output operational
amplifier with a low supply current of only 350 μA maximum
over temperature and supply voltages. It also offers ultralow
offset, drift, and voltage noise combined with very low input
bias current over the full operating temperature range.
With 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), it is 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 to maximize the signal-to-noise ratio and dynamic
range for low power operation. The AD8622 is specified for the
extended industrial temperature range of −40°C to +125°C and
is available in lead-free SOIC and MSOP packages.
