ADA4627-1
ANALOG DEVICES
Low Noise, Low Bias Current, JFET Operational Amplifier

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 temperature range of −40°C to +125°C. It is available in tiny 8-lead LFCSP and 8-lead SOIC packages.
