AD9823KRUZRL7

Overview

The AD9823KRUZRL7 is a Correlated Double Sampler (CDS) designed for digital camera applications. It features a 40 MHz CDS amplifier with a fixed gain of 3.5 dB and an internal voltage reference supply. The device operates from a single 3 V power supply, typically dissipating 50 mW at maximum clock rates. It includes timing control for SHP and SHD sampling clocks and output buffers to drive PCB traces or connect directly to image signal processors like the AD9821.

Procurement Notes

Verify the specific ordering suffix against official Analog Devices documentation to confirm lead-free status and packaging details. Ensure compatibility with system requirements for the 14-lead TSSOP package and single 3 V supply operation before procurement.

Selection Notes

Select this component for CCD signal conditioning where low noise and precise timing are critical. Verify that the input signal range fits within the 850 mV p-p saturation limit and that the 40 MHz maximum clock rate aligns with the target CCD sensor specifications.

Part Context

The AD9823 serves as a dedicated front-end signal conditioner for CCD imagers. It processes analog signals by removing reset noise and amplifying the data level, providing pseudo-differential outputs suitable for interfacing with high-resolution image signal processors in compact imaging systems.

Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Evaluate other CDS amplifiers based on matching gain, bandwidth, and package constraints if replacement is necessary.
