Overview
The ADV7123JSTZ240-RL, produced by Analog Devices Inc., is a high-speed, triple 10-bit digital-to-analog converter (DAC) integrated on a single monolithic chip. This device is designed for high-resolution video and graphics applications, supporting standards such as RS-343A and RS-170. It features three separate 10-bit-wide input ports, a standard TTL input interface, and high impedance analog output current sources. The ADV7123 operates on a single 5 V or 3.3 V power supply and includes additional video control signals such as composite SYNC and BLANK. It also has a power save mode to reduce power consumption when not in use. The device is fabricated in a 5 V CMOS process and is available in a 48-lead LQFP package.
