WM8758CBGEFL/V

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 is housed in a QFN-32 package suitable for surface mount technology. It offers a signal-to-noise ratio of 92.5 dB for the ADC and 100 dB for the DAC, ensuring low noise performance across an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates dual stereo ADC and DAC channels within a single compact package for efficient audio signal conversion.
• Supports standard serial communication interfaces including 2-Wire and 3-Wire configurations for flexible system integration.
• Delivers high dynamic range performance with specified signal-to-noise ratios for both analog input and output stages.

Applications

• Portable multimedia devices requiring stereo audio recording and playback capabilities
• Digital audio systems utilizing PCM codec interfaces for data transmission
• Embedded audio solutions operating within industrial or automotive temperature ranges

Procurement Notes

This component is identified as End-of-Life (EOL) and discontinued by the manufacturer. Availability is restricted, and distributors may not stock this item in all regions. Verification of current lifecycle status and sourcing through authorized channels is essential before design finalization due to potential obsolescence constraints.

Selection Notes

Designers should consider the 48 kHz maximum sampling rate limitation when selecting this part for high-resolution audio applications exceeding standard CD quality. The QFN-32 package requires appropriate thermal management and PCB layout considerations for surface mounting. Verify that the host processor supports the required 2-Wire or 3-Wire serial interface protocols for configuration and data transfer.

Part Context

The WM8758 belongs to the Cirrus Logic WM875x series of audio CODECs. It shares functional similarities with other members like the WM8753 but differs in specific parameters such as maximum sampling rate and package type. This series targets applications needing integrated stereo conversion with minimal external components.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the End-of-Life status, alternative components must be evaluated based on pin compatibility, electrical specifications, and interface requirements rather than direct cross-references.
