AD9823KRUZ

Overview

The AD9823KRUZ is a correlated double sampler (CDS) designed for digital camera applications, manufactured by Analog Devices Inc. It features a 40 MHz CDS amplifier with a fixed gain of 3.5 dB and operates from a single 3 V power supply. The device includes an internal voltage reference supply and timing control for SHP and SHD sampling clocks. It dissipates typically 50 mW at 40 MHz and is housed in a 14-lead TSSOP package.

Feature Summary

• 40 MHz correlated double sampler with fixed 3.5 dB gain
• Low noise optical black clamp circuit
• Single 3 V power supply operation
• Internal voltage reference and timing control

Applications

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

Procurement Notes

Verify the specific ordering suffix KRUZ against official documentation to confirm lead-free status and package variant. Confirm availability through authorized distributors as component lifecycle status may vary. Ensure compatibility with system voltage requirements of 2.7 V to 3.6 V.

Selection Notes

Select this component for CCD signal conditioning where low noise and high-speed sampling are required. Ensure the input signal range does not exceed 850 mV p-p to avoid saturation. Verify that the 14-lead TSSOP package fits the PCB layout constraints and thermal requirements.

Part Context

The AD9823 is part of Analog Devices' image signal processing portfolio, often paired with processors like the AD9821. It provides pseudo-differential outputs for direct connection to differential input ADCs, maintaining signal integrity across separate PC boards.

Replacement Considerations

Check for pin-compatible alternatives if the AD9823KRUZ is discontinued. Verify that any substitute maintains the 40 MHz clock rate and 3.5 dB gain specifications.
