Overview
The ADV7125JST330, 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, and includes additional video control signals such as composite SYNC and BLANK, as well as a power-save mode. The ADV7125 is fabricated in a 5 V CMOS process, ensuring greater functionality with lower power dissipation.
