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 ±± ꢀ to ±1± ꢀ dual supply.
ature range of −40°C to +12±°C. It is available in tiny 8-lead
LFCSP and 8-lead SOIC packages.
The ADA4627-1 is a member of a growing series of high speed,
precision op amps offered by Analog Devices, Inc (see Table 1).
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 μꢀ, drift of less than
1 μꢀ/°C, and noise of only 0.86 μꢀ p-p (0.1 Hz to 10 Hz), the
ADA4627-1 is suited for applications in which error sources
cannot be tolerated.
