GENERAL DESCRIPTION
The ADA4627-1 is a wide bandwidth precision amplifier
featuring low noise, very low offset, drift, and bias current.
Operation is specified from ±5 V to ±15 V dual supply.
The ADA4627-1 provides benefits previously found in few
amplifiers. This amplifier combines the best specifications of
precision dc and high speed ac op amps.
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 is suited for applications in which error sources
cannot be tolerated.
The ADA4627-1 is specified for both the industrial temperature
range of −25°C to +85°C and the extended industrial temper-
