GENERAL DESCRIPTION

The ADV7121/ADV7122 (ADV®) is a video speed, digital-to-analog converter on a single monolithic chip. The part is specifically designed for high resolution color graphics and video systems including high definition television (HDTV). It is also ideal for any application requiring a low cost, high speed DAC function especially in communications. It consists of three, high speed, 10-bit, video D/A converters (RGB), a standard TTL input interface and high impedance, analog output, current sources.
