Overview
The ADV7123KST140, produced by Analog Devices Inc., is a triple high-speed, digital-to-analog converter (DAC) integrated on a single monolithic chip. This component features three high-speed, 10-bit video DACs with complementary outputs, a standard TTL input interface, and a high impedance analog output current source. It is designed to operate with a single 5 V or 3.3 V power supply and clock, making it highly versatile for various high-resolution video and graphics applications. The ADV7123 also includes additional video control signals such as composite SYNC and BLANK, and it has a power save mode to reduce power consumption when not in use.
