WM8152SCDS/V

Overview

The WM8152SCDS/V is a single-channel 16-bit analogue front-end and digitiser designed for CCD and CIS sensors. It supports pixel sample rates up to 12MSPS with an 8-bit programmable gain amplifier and offset adjust. The device features correlated double sampling, reset level clamping, and internally generated voltage references. It operates on a 5V analogue supply and a 5V or 3.3V digital interface, consuming approximately 225mW. Digital output data is provided in a 4-bit wide multiplexed format via a serial control interface.

Feature Summary

• 16-bit ADC with 12MSPS maximum conversion rate
• Integrated signal processing: Reset Level Clamping, Correlated Double Sampling, and Programmable Gain/Offset
• Supports 5V single supply or 5V/3.3V dual supply operation
• 4-bit wide multiplexed digital output data bus

Applications

• Flatbed and sheetfeed scanners
• USB compatible scanners
• Multi-function peripherals
• High-performance CCD sensor interfaces

Procurement Notes

Verify the specific suffix 'V' indicates the lead-free, commercial temperature range (0°C to 70°C) variant in the 20-lead SSOP package. Confirm availability status as distribution channels may list this component as obsolete or limited stock. Ensure the design supports the required 4-bit multiplexed output timing and serial control interface protocols.

Selection Notes

Select this component for applications requiring high-speed digitization of CCD or CIS signals with integrated analog conditioning. Ensure the system can accommodate the 4-bit multiplexed data output format rather than parallel interfaces. Verify power supply requirements match the 5V analog and 5V/3.3V digital specifications to maintain optimal performance and noise characteristics.

Part Context

The WM8152 belongs to Cirrus Logic's family of high-performance analog-to-digital converters tailored for imaging applications. It integrates the complete analog signal chain, including PGA and CDS, reducing external component count compared to discrete solutions. This integration makes it suitable for compact scanner designs where board space and signal integrity are critical constraints.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should evaluate other single-channel 16-bit AFEs from Cirrus Logic or competitors if this specific package or pinout is unavailable, ensuring compatibility with the 4-bit multiplexed output requirement.
