ADA4637-1BRZ

ADA4637-1 is a single channel, wide bandwidth precision amplifier featuring low noise, very low offset, drift, and bias current. This amplifier combines the best specifications of precision dc and high speed ac op-amps. It is a decompensated version of the ADA4627-1 and is stable at a noise gain of 5 or greater. With a typical offset voltage of only 70μV, drift of less than 1μV/°C, and noise of only 0.86μV p-p (0.1Hz to 10Hz), this device is well suited for applications where error sources cannot be tolerated. It is used in applications such as high impedance sensors, photodiode amplifier, precision instrumentation, phase-locked loop filters, high end, professional audio, DAC output amplifier, ATE, medical.
