LM9822CCWM/NOPB

Specialized ICS Overview

The LM9822CCWM/NOPB is a high-performance Analog Front End (AFE) for image sensor processing systems, manufactured by Texas Instruments. It performs analog and mixed-signal functions including correlated double sampling, color-specific gain and offset correction, and analog-to-digital conversion to digitize outputs from CCD and CIS sensors. The device features a 14-bit ADC with a pixel conversion rate of 6 MHz. It operates with an analog supply voltage of 5V ±5% and a digital I/O supply of 3.3V ±10% or 5V ±5%. Typical power dissipation is 375mW. The component is housed in a 28-SOIC package.

Specialized ICS Feature Summary

• Integrated 14-bit, 6MHz ADC for high-speed data acquisition
• Digitally programmable gain and offset for Red, Green, and Blue channels
• Correlated Double Sampling (CDS) capability for noise reduction in CCD sensors
• Internal voltage reference generation and TTL/CMOS compatible I/O

Specialized ICS Applications

• Color flatbed document scanners
• Color sheetfed scanners
• Multifunction imaging products
• Digital copiers
• General purpose linear array imaging

Specialized ICS Procurement Notes

Verify the component status as discontinued via official Texas Instruments documentation. Confirm that the NOPB suffix indicates lead-free and RoHS compliance. Ensure the 28-SOIC package dimensions match the design requirements. Check for any Product Change Notifications (PCN) regarding assembly site changes or material substitutions prior to procurement.

Specialized ICS Selection Notes

Select this AFE for applications requiring simultaneous three-channel signal processing with integrated CDS. Ensure the system design supports the required 5V analog and 3.3V/5V digital supplies. Verify that the host controller can interface with the serial configuration registers and handle the 8-bit multiplexed data output stream synchronized with the MCLK input.

Specialized ICS Part Context

This part belongs to the LM9822 family of scanner analog front ends. The CCWM designation specifies the commercial temperature range (0°C to +70°C) and the SOIC-28 package. The NOPB suffix denotes a lead-free, halogen-free version compliant with RoHS directives, replacing older non-compliant variants within the same functional specification.
