AD9826KRSZRL

Overview

The AD9826KRSZRL is a complete analog signal processor for imaging applications, featuring a 3-channel architecture designed to sample and condition outputs from trilinear color CCD arrays. It integrates input clamps, Correlated Double Samplers (CDS), offset DACs, and Programmable Gain Amplifiers (PGA) multiplexed to a high-performance 16-bit A/D converter. The device operates at speeds up to 15 MSPS with 16-bit resolution, supporting 3V/5V digital I/O compatibility. Key parameters include a maximum conversion rate of 30 MSPS in 3-channel mode, ±16 LSB INL, ±0.5 LSB DNL, and typical power consumption of 400 mW. It utilizes a 3-wire serial interface for register programming and is housed in a 28-lead SSOP package.

Feature Summary

• Integrates three independent channels with input clamping, correlated double sampling, offset adjustment, and programmable gain amplification.
• Features a high-performance 16-bit ADC with multiplexed byte-wide output and optional single-byte mode.
• Supports multiple operating modes including 3-channel, 2-channel, and 1-channel configurations with CDS or Sample-and-Hold functionality.
• Includes internal voltage reference and low-power CMOS design with available power-down mode.

Applications

• Flatbed document scanners
• Digital copiers and multifunction peripherals
• Infrared imaging applications
• Machine vision systems

Procurement Notes

Verify the specific suffix 'RL' indicates reel packaging when sourcing components. Confirm that the device meets RoHS3 compliance standards as specified in the manufacturer documentation. Ensure that the 28-lead SSOP footprint matches the target PCB layout requirements. Check for any end-of-life notices or obsolescence warnings associated with this part number before finalizing procurement plans.

Selection Notes

Select the AD9826KRSZRL for applications requiring precise conditioning of trilinear CCD signals. Consider the 16-bit resolution and low noise performance for high-quality image capture. Evaluate the need for CDS versus SHA modes based on the sensor type. Ensure supply voltages align with the specified AVDD and DRVDD ranges for optimal operation.
