GENERAL DESCRIPTION
The ADA4627-1/ADA4637-1 are wide bandwidth precision
amplifiers featuring low noise, very low offset, drift, and bias
current. The parts operate from ±5 V to ±15 V dual supply.
The ADA4627-1/ADA4637-1 provide benefits previously found
in few amplifiers. These amplifiers combine the best specifications
of precision dc and high speed ac op amps. The ADA4637-1 is
a decompensated version of the ADA4627-1 and is stable at a
noise gain of 5 or greater.
With a typical offset voltage of only 70 µV, drift of less than
1 µV/°C, and noise of only 0.86 µV p-p (0.1 Hz to 10 Hz), the
ADA4627-1/ADA4637-1 are suited for applications where error
sources cannot be tolerated.
The ADA4627-1/ADA4637-1 are specified for both the
industrial temperature range of −25°C to +85°C and the
extended industrial temperature range of −40°C to +125°C. The
ADA4627-1 is available in tiny 8-lead LFCSP and 8-lead SOIC
packages, and the ADA4637-1 is available in tiny 8-lead SOIC
packages.
The ADA4627-1/ADA4637-1 are members of a growing series
of high speed, precision op amps offered by Analog Devices,
Inc. (see Table 1).
