The SDA7123 is a triple high speed, digital-to-analog converter on a single monolithic chip. It consists of three high speed, 10-bit, video DACs with complementary outputs, a standard TTL input interface, and a high impedance, analog output current source. The SDA7123 has three separate 10-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 SDA7123 has additional video control signals, composite SYNC and BLANK. The SDA7123 also has a power save mode. The SDA7123 is fabricated in a 5 V CMOS process. Its monolithic CMOS construction ensures greater functionality with lower power dissipation. The SDA7123 is available in a 48-lead LQFP package.
