WM8750CBLGEFL

Overview

The WM8750CBLGEFL 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), supporting a resolution of 24 bits and sampling rates up to 96 kHz. The device operates within a supply voltage range of 1.42 V to 3.6 V and functions reliably across an industrial temperature range from -25°C to +85°C. It utilizes a serial interface compatible with 2-Wire and 3-Wire protocols. The component is housed in a 32-pin QFN package with surface mount technology. Key performance metrics include a signal-to-noise ratio of 88 dB for the ADC and 97 dB for the DAC.

Feature Summary

• Integrates dual ADC and dual DAC channels for complete stereo audio processing.
• Supports high-resolution 24-bit data conversion at sampling frequencies up to 96 kHz.
• Features low-voltage operation suitable for battery-powered portable devices.
• Includes integrated headphone output drivers for direct speaker connection.

Applications

• Portable audio players and media devices
• Mobile communication handsets
• Digital voice recording equipment

Procurement Notes

Verify component authenticity through authorized distributors or certified suppliers due to obsolete status. Check manufacturing date codes and lot numbers against current inventory records. Ensure proper handling procedures are followed as the device may be sensitive to electrostatic discharge. Confirm that the specific suffix matches the required packaging format for your assembly line.

Selection Notes

Select this component when a stereo CODEC with integrated headphone amplifiers is required for space-constrained designs. Compare pin compatibility and electrical specifications with similar models like the WM8753 if additional PCM codec functionality is needed. Verify that the 32-pin QFN footprint aligns with existing PCB layouts. Consider thermal management requirements given the operating temperature range and power dissipation characteristics.

Part Context

This part belongs to the WM8750 series of audio CODECs from Cirrus Logic, formerly Wolfson Microelectronics. The series is known for high-performance audio conversion in compact packages. The WM8750CBLGEFL variant specifically denotes the commercial grade temperature range and the reel packaging option. It serves as a legacy solution for established audio hardware designs requiring reliable stereo conversion.
