330MHz Triple 8-Bit High Speed Video DAC

The ADV7125 (ADV®) is a triple high speed, digital-to-analog converter (DAC) 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 device functional. The ADV7125 has additional video control signals, composite SYNC and BLANK as well as a power save mode.

The ADV7125 is fabricated in a 5 V CMOS process. Its monolithic CMOS construction ensures greater functionality with lower power dissipation. The ADV7125 is available in 48- lead LQFP and 48-lead LFCSP packages.
