ADDI7100BCPZ

Overview

The ADDI7100BCPZ 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. It is housed in a space-saving 32-lead, 5 mm × 5 mm LFCSP package.

Feature Summary

• Integrates a 45 MHz correlated double sampler with programmable gain settings
• Includes a low noise optical black clamp circuit for precise black level correction
• Features a 12-bit ADC with no missing codes guaranteed across operating conditions
• Utilizes a 3-wire serial digital interface for internal register configuration

Applications

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

Procurement Notes

Verify the specific suffix BCPZ corresponds to the 32-lead LFCSP packaging and commercial temperature range. Confirm that the component meets RoHS compliance standards as indicated in official documentation. Ensure compatibility with the required 3 V power supply rails and serial interface timing constraints before integration into the design.

Selection Notes

Select this component for systems requiring a compact solution for processing interlaced or progressive scan CCD arrays. It serves as a pin-compatible upgrade for the AD9945. Consider its 125 mW power consumption and 3 V operation when designing power delivery networks. Verify that the 45 MHz sampling rate aligns with the target CCD pixel clock requirements.

Part Context

This part belongs to the Analog Devices ADDI7100 series of CCD signal processors. It is designed to replace older generation components like the AD9945 while offering enhanced integration. The device consolidates analog conditioning and digitization into a single chip, reducing board space and simplifying system architecture for portable imaging applications.

Replacement Considerations

The ADDI7100 is documented as a pin-compatible upgrade for the AD9945.
