AD9985A Rev. 0 is an analog interface for flat panel displays with a conversion rate of 110 MSPS / 140 MSPS. It features variable analog input bandwidth control, variable SOGIN bandwidth control, and automated clamping level adjustment.
The AD9985A is an 8‑bit, 140 MSPS monolithic analog interface designed for capturing RGB graphics signals from PCs and workstations. It supports up to SXGA resolution (1280 × 1024 @ 75 Hz) with a 300 MHz analog bandwidth and offers programmable gain, offset, and clamp control via a 2‑wire serial interface.
The document provides full specifications, absolute maximum ratings, pin configurations, design guidelines, and PCB layout recommendations to help designers integrate the device into flat‑panel display systems.
