Overview
The AD9883AKSTZ-110, produced by Analog Devices Inc., is a highly integrated 8-bit, 110 MSPS (mega-samples per second) analog-to-digital converter (ADC) designed for capturing and digitizing RGB graphics signals. This device is optimized for use in various display applications, including LCD monitors, projectors, and high-performance video scan converters. Implemented in a high-performance CMOS process, it supports pixel rates up to 110 MHz and includes features such as internal 1.25 V reference, phase-locked loop (PLL), and programmable gain, offset, and clamp control. The AD9883A operates over an industrial temperature range of –40°C to +85°C and has a typical power dissipation of 500 mW, making it suitable for a wide range of environments.
