WM8758CBGEFL/RV

Overview

The WM8758CBGEFL/RV is a stereo audio CODEC manufactured by Cirrus Logic, designed for high-fidelity digital audio processing. It integrates two analog-to-digital converters (ADCs) and two digital-to-analog converters (DACs), supporting a resolution of 24 bits. The device operates with a supply voltage ranging from 2.5 V to 3.6 V and supports sampling rates up to 48 kHz. It features a serial interface compatible with 2-Wire and 3-Wire protocols. The component provides a signal-to-noise ratio of 92.5 dB for the ADC and 100 dB for the DAC. It is housed in a QFN-32 package suitable for surface mount technology and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates stereo ADC and DAC paths with advanced digital signal processing capabilities
• Supports standard serial audio interfaces for flexible system integration
• Includes internal power management features to reduce external component count

Applications

• Portable multimedia devices requiring stereo audio input and output
• Digital voice recording equipment
• Consumer audio playback systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm RoHS compliance documentation matches specific batch requirements. Check for moisture sensitivity level indicators on packaging prior to installation. Ensure storage conditions adhere to specified humidity limits to prevent solderability issues during reflow processes.

Selection Notes

Select this component when a compact stereo CODEC with integrated ADC and DAC is required for low-voltage applications. Consider the QFN-32 package constraints for PCB layout and thermal dissipation. Evaluate the 48 kHz maximum sampling rate against application bandwidth needs. Verify compatibility with available serial interface protocols before finalizing the design.
