AD9940BCPZRL

Overview

The AD9940BCPZRL is a high-speed, single-channel correlated double sampler (CDS) with an integrated timing driver, manufactured by Analog Devices Inc. It operates from a single 2.7 V to 3.6 V supply and features a 56 MHz CDS amplifier with 6 dB fixed gain. The device includes a Precision Timing core providing 0.37 ns resolution for high-speed clock adjustment. Power dissipation is typically 105 mW at 2.7 V without H/RG drivers. It is housed in a 48-lead LQFP package.

Feature Summary

• 56 MSPS Correlated Double Sampler (CDS) with 6 dB fixed gain
• On-chip horizontal and RG timing driver with programmable drive strength
• Precision Timing core with 0.37 ns resolution at 56 MSPS
• Single-supply operation (2.7 V min) with low power CMOS technology

Applications

• Professional HDTV camcorders
• Professional/high-end digital cameras
• Broadcast cameras
• Industrial high-speed cameras
• High-speed data-acquisition systems

Procurement Notes

Verify the specific ordering suffix BCPZRL against the manufacturer's current datasheet to confirm package type and tape/reel configuration. Ensure compatibility with system voltage requirements of 2.7 V to 3.6 V. Check for RoHS compliance status as per the latest revision. Confirm availability through authorized distributors as lead times may vary.

Selection Notes

Select this component for CCD imaging systems requiring precise timing control and noise reduction via CDS. Ensure the design supports a single 3 V supply. Verify that the PCB layout accommodates the 48-lead LQFP package. Consider the internal drive capabilities for H1-H4 and RG outputs to minimize external components.

Part Context

The AD9940 is part of Analog Devices' high-speed analog front-end family designed for CCD sensors. It integrates the CDS and timing generation functions, reducing board space and complexity. The BC prefix indicates a specific temperature range or package variant within the AD9940 series.

Replacement Considerations

Check for direct pin-compatible replacements in the AD9940 series. Verify if alternative packages like LFCSP are available for the same functionality. Ensure any substitute maintains the 56 MSPS speed and single-supply operation.
