AD9985KSTZ-110

Specialized Overview

The AD9985KSTZ-110 is an 8-bit, 140 MSPS analog interface IC optimized for capturing RGB graphics signals from personal computers and workstations. It features a triple ADC with internal 1.25 V reference, a PLL, and programmable gain, offset, and clamp control. The device supports resolutions up to SXGA (1280 × 1024 at 75 Hz) with a 300 MHz analog bandwidth. Operating on a single 3.3 V supply, it includes full sync processing, hot-plug detection, and a 2-wire serial interface for configuration. It is housed in an 80-lead LQFP package and operates within a temperature range of –40°C to +85°C.
