ADA4637-1

30 V, 80 MHz, Low Noise, Low Bias Current, JFET Op Amp
Manufactured by:

Product Details

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 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.

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.

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 are members of a growing series of high speed, precision op amps offered by Analog Devices, Inc.

I used this for an audio application, the overall performance was sastifactory, espescially in the gain stage. But then, oscillation will occur when using as buffer, so for buffer stage, the brother ADA4627-1 is recommended

One of the best audio opamp around
I used this opamp to built a high quality affordable phone pre opamp. I have to say that this opamps is in my top three opamps ever. I performs better for audio than the famous 627 which is far more difficult to get. I would recommend this opamp for all audio purposes when high quality sound (natural en detailed) reproduction is required.
