ADA4627/ADA4637 Wide Bandwidth Precision Amplifiers
Analog Devices' 36 V, 80 MHz, low noise, and low bias current JFET op amp
ADI's ADA4627 and ADA4637 are wide bandwidth precision amplifiers that feature low noise and very low offset, drift, and bias current. The device operates from ±5 V to ±15 V dual supply. Combining the best specifications of precision DC and high-speed AC op amps, these amplifiers provide benefits previously found in few amplifiers.
The ADA4637 is a decompensated version of the ADA4627 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 µVPP (0.1 Hz to 10 Hz), it is suited for applications where error sources cannot be tolerated. The ADA4627/ADA4637 is specified for both an industrial temperature range of -25°C to +85°C and an extended industrial temperature range of -40°C to +125°C. These amplifiers are available in a tiny 8-lead SOIC package as well as 8-lead LFSCP package. The ADA4627/ADA4637 was designed for high impedance sensors, photodiode, and precision instrumentational applications.
