ADDI7100BCPZRL

Overview

The ADDI7100BCPZRL is a complete analog front-end signal processor for charge-coupled device applications. It features a single-channel architecture with a 45 MHz correlated double sampler, a variable gain amplifier providing 6 dB to 42 dB gain, and a 12-bit analog-to-digital converter. The device operates from a single 3 V supply, typically dissipating 125 mW, and is housed in a 32-lead LFCSP package.

Feature Summary

• Integrates a 45 MHz correlated double sampler with programmable gain stages
• Includes an optical black clamp circuit for low noise offset correction
• Features a 12-bit ADC with guaranteed no missing codes
• Configurable via a 3-wire serial digital interface

Applications

• Digital still cameras
• Digital video camcorders
• PC cameras
• Portable CCD imaging devices
• CCTV cameras

Procurement Notes

Verify the specific suffix RL against official documentation to confirm reel packaging requirements. Confirm current availability status as distribution channels may vary. Ensure compatibility with existing system timing generators and serial interface protocols before integration.

Selection Notes

Select this component for systems requiring integrated CCD signal conditioning without external discrete amplifiers. Evaluate power consumption constraints against the typical 125 mW dissipation. Verify that the 3 V single-supply operation aligns with available system voltage rails.

Part Context

This part belongs to the ADDI7100 series of analog front-end processors designed specifically for CCD image sensors. It serves as a pin-compatible upgrade for previous generations like the AD9945, offering enhanced integration of sampling, amplification, and conversion functions within a compact footprint.

Replacement Considerations

The datasheet identifies the ADDI7100 as a pin-compatible upgrade for the AD9945. Verify register mapping and timing specifications when transitioning between these models.
