AD9886KS-140

Overview

The AD9886KS-140 is an analog flat panel interface device manufactured by Analog Devices Inc. It integrates a triple 8-bit ADC with a sampling rate of 140 MSPS, designed for capturing RGB graphics signals. The component features a full-power analog bandwidth of 500 MHz and operates on a single 3.3 V power supply. It includes internal circuitry for sync processing, midscale clamping, and programmable gain and offset controls. The device supports resolutions up to UXGA at 75 Hz and provides three-state CMOS outputs compatible with 2.5 V to 3.3 V logic levels.

Feature Summary

• Triple 8-bit ADC with 140 MSPS maximum conversion rate
• 500 MHz full-power analog bandwidth supporting high-resolution displays
• Integrated PLL for pixel clock generation from HSYNC and COAST signals
• Single 3.3 V power supply operation with typical power consumption under 1 W

Applications

• LCD monitors and projectors
• Plasma display panels
• RGB graphics processing systems
• Scan converters

Part Context

The AD9886KS-140 belongs to the AD9888 family of analog front-end interfaces. While the AD9888 series typically supports rates up to 170 MSPS, the AD9886 variant is specified for 140 MSPS operation. This part number represents a specific speed bin within the broader AD9888 product line, sharing similar architectural features such as the triple ADC structure and integrated sync processing capabilities.

Replacement Considerations

The AD9888KS-140 serves as a direct functional replacement, offering higher performance with a 170 MSPS rating while maintaining pin compatibility and feature sets. Designers should verify that the increased bandwidth and clock speed align with their system timing requirements.
