Overview
The ADV7125WBSTZ170-RL is a high-speed, triple digital-to-analog converter (DAC) produced by Analog Devices Inc. This component is integrated on a single monolithic chip and features three 8-bit video DACs with complementary outputs. It is designed to operate with a standard TTL input interface and a high impedance, analog output current source. The device supports a single +5 V or +3.3 V power supply and includes additional video control signals such as composite SYNC and BLANK, as well as a power save mode.
