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 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 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.

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).

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.
