WM8255SEFL

Overview

The WM8255SEFL is a single-channel 16-bit analogue front-end and digitiser IC designed for CCD and CIS sensors. It processes signals at up to 12 MSPS, featuring Reset Level Clamping (RLC), Correlated Double Sampling (CDS), an 8-bit Programmable Gain Amplifier (PGA), and an 8-bit offset DAC. The device supports line-by-line colour processing via internal multiplexers and includes an RGB LED current drive with PWM control. It operates on a 5.75V analogue supply and a 3.3V digital interface, housed in a 28-lead QFN package.

Feature Summary

16-bit ADC with 12 MSPS conversion rate
Integrated signal processing: RLC, CDS, 8-bit PGA, and 8-bit offset DAC
RGB LED current drive with coarse/fine adjustment and PWM control
Multiplexed 2-bit or 4-bit digital output format

Applications

Flatbed scanners
Sheetfeed scanners
USB compatible scanners
Multi-function peripherals

Procurement Notes

Verify the specific suffix 'SEFL' against the manufacturer's ordering information table, as datasheets typically list variants like 'BGEFL'. Confirm the package type matches the required PCB footprint and check for RoHS compliance status in the latest production data.

Selection Notes

Select this component for applications requiring high-speed digitisation of CCD/CIS sensors with integrated LED driving. Ensure the system design accommodates the dual supply voltages (5.75V AVDD1 and 3.3V DVDD) and the 28-lead QFN thermal requirements.

Part Context

This part belongs to the Wolfson Microelectronics (now Cirrus Logic) family of image sensor interface devices. It is specifically engineered to simplify scanner designs by combining the AFE and LED driver functions into a single chip, reducing external component count compared to discrete solutions.

Replacement Considerations

Direct replacements are not explicitly listed in the provided documentation. Evaluate other single-channel CIS/CCD AFEs from Cirrus Logic or competitors that offer similar 16-bit resolution, 12 MSPS speed, and integrated LED drivers.
