The ADV7120 is a digital-to-analog video converter on a single monolithic chip from Analog Devices. It is specifically designed for high resolution color graphics and video systems. It also ideal for any high speed communications type applications requiring low cost, high speed DACs.
The ADV7120 is a CMOS triple 8‑bit video digital‑to‑analog converter designed for high‑resolution color graphics and video systems. It provides three independent RGB current‑output DACs, TTL‑compatible video inputs, and optional sync and blanking control.
The device operates from a single +5 V supply, offers up to 80 MHz clock rates, and is supplied in 40‑pin DIP, 44‑pin PLCC and 48‑lead TQFP packages. Detailed specifications, timing characteristics, pin functions and recommended operating conditions are provided in this handbook.
