Overview
The ADV7123KSTZ50 is a high-speed, triple 10-bit digital-to-analog converter (DAC) produced by Analog Devices Inc. This component is integrated on a single monolithic chip and is designed for high-performance video applications. It features three high-speed, 10-bit video DACs with complementary outputs, a standard TTL input interface, and a high impedance analog output current source. The ADV7123KSTZ50 operates with a single 5 V or 3.3 V power supply and supports additional video control signals such as composite SYNC and BLANK. It also includes a power save mode to reduce power consumption when not in use.
