Overview
The ADA4817-1ARDZ is a single, unity-gain stable, ultrahigh speed, voltage feedback operational amplifier developed by Analog Devices Inc. This amplifier utilizes the proprietary extra fast complementary bipolar (XFCB) process, enabling it to achieve ultralow noise and very high input impedances. It features FET inputs and is designed for applications requiring high speed and low noise, such as photodiode amplifiers, data acquisition front ends, instrumentation, filters, ADC drivers, and output buffers.
