GENERAL DESCRIPTION
The AD8624 is a quad, precision rail-to-rail output operational
amplifier with a low supply current of only 350 μA maximum
over temperature and supply voltages. It offers low offset, drift,
and voltage noise combined with very low input bias currents
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 11nV/√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 ADA8624 to
maximize the signal-to-noise ratio and dynamic range for low
power operation.
The AD8624 is specified over the extended industrial
temperature range of −40°C to +125°C. The AD8624 is available
in an 14-lead TSSOP and 16-lead LFCSP (4x4x0.85mm)
surface-mount package. The AD8624 is part of a growing
family of 36 V, low power op amps from Analog Devices.
