Overview
The ADV7125KSTZ50, produced by Analog Devices Inc., is a high-speed, triple 8-bit digital-to-analog converter (DAC) integrated on a single monolithic chip. This device is designed for high-performance video applications and features three separate 8-bit-wide input ports, each corresponding to red, green, and blue video signals. It operates with a single +5 V or +3.3 V power supply and includes a standard TTL input interface and high impedance analog output current sources. The ADV7125 is fabricated in a 5 V CMOS process, ensuring lower power dissipation and greater functionality. It is available in 48-lead LQFP and 48-lead LFCSP packages.
