Overview
The AD8045ACPZ-REEL7, produced by Analog Devices Inc., is a high-speed voltage feedback amplifier. It is fabricated using Analog Devices' second-generation extra fast complementary bipolar (XFCB) process, which enables high performance characteristics such as low noise, ultralow distortion, and a high slew rate. This amplifier is particularly suited for applications requiring high dynamic range, precision, and high speed.
