Overview
The AD8075ARUZ, produced by Analog Devices Inc., is a high-speed triple video buffer amplifier. This device is designed with a gain of +2 and features a –3 dB full signal bandwidth in excess of 550 MHz. It is particularly suited for applications requiring high video quality, such as RGB buffering or driving in LCD and plasma displays. The AD8075ARUZ consumes less than 30 mA on a ±5 V supply and offers a fast output disable feature, allowing the outputs to be put into a high impedance state. This feature is beneficial for building larger input arrays while minimizing output loading when the channels are disabled.
