GENERAL DESCRIPTION
PRODUCT HIGHLIGHTS
The ADV7125 is a triple high speed, digital-to-analog converter on a single monolithic chip. It consists of three high speed, 8-bit video DACs with complementary outputs, a standard TTL input interface, and a high impedance, analog output current source. The ADV7125 has three separate 8-bit-wide input ports. A single 5 V/3.3 V power supply and clock are all that are required to make the part functional. The ADV7125 has additional video control signals, composite SYNC and BLANK, as well as a powersave mode. The ADV7125 is fabricated in a 5 V CMOS process. Its monolithic CMOS construction ensures grea……
