ADV7128 is a high-speed, 10-bit video D/A converter that is ideal for power and cost-sensitive communication applications.
The ADV7128 video DAC converts 10‑bit digital video data to analog current‑mode outputs. It operates up to 80 MHz, supports RS‑343A, RS‑170 and SMPTE 240M video standards, and is used in HDTV, high‑resolution graphics, digital radio modulation and other video applications.
Key features include a single +5 V supply, TTL‑compatible inputs, programmable gray‑scale current, and a 28‑pin SOIC package. The datasheet provides detailed specifications, pin‑out diagrams, timing characteristics, absolute maximum ratings, and PCB layout recommendations to ensure low noise and reliable operation.
