WM8255BGEFL/V

Overview

The WM8255BGEFL/V is a single-channel 16-bit analogue front end (AFE) and digitiser IC designed for CCD and CIS sensors. It processes video signals at pixel sample rates up to 12 MSPS, featuring Reset Level Clamping, Correlated Double Sampling, an 8-bit Programmable Gain Amplifier, and an 8-bit Offset DAC. The device includes an internal 4-bit DAC for reference generation and RGB LED current drive capabilities. It operates with a typical 5.75V analogue supply and 3.3V digital interface, outputting data in a 2-bit or 4-bit multiplexed format via a 3-wire serial control interface.

Feature Summary

16-bit ADC with 12 MSPS conversion rate
Integrated signal processing: CDS, RLC, 8-bit PGA, and 8-bit Offset DAC
RGB LED current drive using current and PWM functionality
28-lead QFN package (4x4x0.85mm)

Applications

Flatbed scanners
Sheetfeed scanners
USB compatible scanners
Multi-function peripherals

Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm packaging type. The 'V' suffix indicates tube packaging, while '/RV' denotes tape and reel. Confirm that the component meets the required Moisture Sensitivity Level (MSL3) and peak soldering temperature specifications for the intended assembly process.

Selection Notes

Select this component for applications requiring a single-channel AFE for CCD or CIS sensors. Ensure the system design supports the required 5.75V analogue supply and 3.3V digital I/O levels. Verify that the input video signal range fits within the 0.24Vp-p to 2.56Vp-p full-scale limits after gain adjustment. Check thermal performance requirements against the junction-to-ambient resistance of the 4x4mm QFN package.

Part Context

The WM8255BGEFL/V belongs to the Wolfson Microelectronics (now Cirrus Logic) WM8255 family of image sensor interfaces. It is functionally identical to the WM8255BGEFL/RV, differing only in the shipping packaging configuration. The device is part of the broader portfolio of analog front ends designed for high-performance imaging applications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult the manufacturer's official replacement guide or contact technical support for verified cross-references.
