Overview
The WM8750CJLGEFL is a stereo audio CODEC manufactured by Cirrus Logic, designed for portable and high-fidelity audio applications. It integrates two analog-to-digital converters (ADCs) and two digital-to-analog converters (DACs) with a resolution of 24 bits. The device supports sampling rates up to 96 kHz and utilizes a serial interface compatible with 2-Wire or 3-Wire protocols. Operating voltage ranges from 1.42 V to 3.6 V, with an operating temperature range of -25°C to +85°C. It is housed in a 32-pin QFN package.
Feature Summary
- Integrates stereo ADC and DAC channels for complete audio signal processing
- Supports high-resolution 24-bit audio conversion at sampling rates up to 96 kHz
- Features low-voltage operation suitable for battery-powered portable devices
- Includes integrated headphone amplifier and speaker driver outputs
Applications
- Portable audio players and media devices
- Mobile communication handsets
- Digital voice recording equipment
- Automotive infotainment systems
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Check for obsolescence status as the WM8750 series has been discontinued by Cirrus Logic. Ensure compatibility with existing PCB footprints and design-in documentation before procurement.
Selection Notes
Compare SNR and THD+N specifications against alternative codecs if higher fidelity is required. Verify power supply requirements match the target system's voltage rails. Confirm interface protocol compatibility with the host processor. Consider thermal performance within the QFN-32 package for the specific application environment.
Part Context
This component belongs to the WM8750 family of stereo CODECs from Cirrus Logic. It shares architectural similarities with other models in the series but differs in pinout, packaging, and specific electrical characteristics. The CJL suffix typically denotes specific tape and reel packaging or regional variants within the broader product line.
Replacement Considerations
The WM8750 series is obsolete. Potential replacements include the WM8753 or WM8758, though these require schematic and firmware adjustments due to differences in pin configuration, additional DAC channels, and updated feature sets.
