WM8731CSEFL/R

Overview

The WM8731CSEFL/R is a stereo audio CODEC manufactured by Cirrus Logic, designed for portable and battery-powered applications. It integrates two ADCs and two DACs with a resolution of 24 bits and supports sampling rates up to 96 kHz. The device operates on a single power supply ranging from 1.8 V to 3.6 V. It features an SNR of 90 dB for the ADC and 100 dB for the DAC. Communication is handled via serial interfaces supporting 2-Wire and 3-Wire protocols. The component is housed in a QFN-28 package suitable for surface mount installation.

Feature Summary

Integrates high-performance stereo analog-to-digital and digital-to-analog converters within a single chip
Supports flexible digital interface connectivity through standard serial communication protocols
Optimized for low-power operation using a single voltage supply range

Applications

Portable media players and handheld audio devices
Mobile communication terminals requiring integrated audio processing
Battery-operated consumer electronics with stereo audio output needs

Procurement Notes

Verify the specific suffix CSEFL/R against official manufacturer documentation to confirm pinout compatibility and electrical characteristics. Confirm current lifecycle status as distribution availability may be limited due to obsolescence. Ensure sourcing channels provide authentic components with traceable manufacturing records to prevent counterfeit risks.

Selection Notes

Select this component when a compact stereo codec with high signal-to-noise ratio is required for space-constrained designs. Evaluate power consumption requirements against the 1.8 V to 3.6 V operating range. Consider the QFN-28 package dimensions for PCB layout constraints and thermal management capabilities during the design phase.

Part Context

This part belongs to the WM8731 series of audio CODECs from Cirrus Logic. It shares core functional specifications with variants like the WM8731LSEFL/R but differs in packaging or temperature grade. The series is characterized by its integration of stereo conversion capabilities and low-power architecture for mobile applications.

Replacement Considerations

The WM8904CGEFL/V is listed as a potential replacement option. Verify functional equivalence regarding interface compatibility and power specifications before substitution.
