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.
