Overview
The ADV7125BCPZ170-RL, produced by Analog Devices Inc., is a triple high-speed digital-to-analog converter (DAC) integrated on a single monolithic chip. This device features three high-speed, 8-bit video DACs with complementary outputs, a standard TTL input interface, and a high impedance analog output current source. It operates with a single +5 V or +3.3 V power supply and clock, making it versatile for various video applications. The ADV7125 also includes additional video control signals such as composite SYNC and BLANK, as well as a power save mode. Fabricated in a 5 V CMOS process, this device ensures greater functionality with lower power dissipation and is available in 48-lead LQFP and 48-lead LFCSP packages.
