Overview
The AD8397ARZ, produced by Analog Devices Inc., is a dual-channel voltage feedback operational amplifier designed to drive heavy loads with excellent linearity. Fabricated using Analog Devices' high-speed extra fast complementary bipolar high voltage (XFCB-HV) process, this amplifier features a common-emitter, rail-to-rail output stage. This configuration allows the output to swing to within 0.5 V of either rail while driving a 25 Ω load, making it ideal for applications requiring large signal swings into heavy loads.
