AD9983AKCPZ-140

Specialized Overview

The AD9983AKCPZ-140 is a high-performance, monolithic 8-bit display interface optimized for capturing YPbPr video and RGB graphics signals. It features three analog-to-digital converters with a maximum conversion rate of 140 MSPS and a full power analog bandwidth of 300 MHz. The device supports HDTV modes up to 1080i/720p and graphics resolutions up to SXGA (1280 x 1024 at 75 Hz). Key specifications include an input voltage range of 0.5 V to 1.0 V p-p, differential nonlinearity of ±0.85 LSB, and integral nonlinearity of 1.45/-2.60 LSB. Power supplies are 1.8 V for analog/digital logic and 1.8 V to 3.3 V for outputs. It operates within a temperature range of 0°C to 70°C in an 80-lead LQFP package.

Specialized Procurement Notes

Verify the component status as End-of-Life (EOL) through official Analog Devices channels before procurement planning. Confirm that the specific ordering suffix corresponds to the required performance grade and package variant. Ensure compliance with RoHS directives and humidity sensitivity handling protocols during storage and assembly.

Specialized Selection Notes

Select this component when designing systems requiring digitization of analog RGB or YPbPr signals for digital displays. It is suitable for applications needing integrated signal conditioning, clamping, and clock regeneration without external discrete components. Consider the 80-lead LQFP footprint and thermal requirements during PCB layout.
