AD8079ARZ

AD8079 is a dual, low power, high speed buffer designed to operate on ±5V supply. This pinout offers excellent input and output isolation compared to the traditional dual amplifier pin configuration. The B grade gain of +2.2 compensates for gain loss through a system by providing a single-point trim. Using active laser trimming of this resistor, the AD8079 guarantees tight control of gain and channel-channel gain matching. With its performance and configuration, the AD8079 is well suited for driving differential cables and transformers. Its low distortion and fast settling are ideal for buffering high speed dual or differential A-to-D converters. It features a unique transimpedance linearization circuitry. Application includes differential A-to-D driver, video line driver, differential line driver, professional cameras, video switchers, special effects, RF receivers.
