WM8750CJLGEFL/R

Overview

The WM8750CJLGEFL/R is a stereo audio CODEC manufactured by Cirrus Logic, designed for high-fidelity audio processing. It features 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 power supply voltage range of 1.42 V to 3.6 V. It utilizes a serial interface compatible with 2-Wire and 3-Wire protocols for control and data transmission. The component is housed in a 32-pin QFN package suitable for surface mount technology. Performance metrics include a signal-to-noise ratio of 88 dB for the ADC and 97 dB for the DAC, with total harmonic distortion plus noise specified at -80 dB for the ADC and -85 dB for the DAC.

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and specific lot traceability requirements before procurement. Ensure storage conditions meet humidity sensitivity levels to prevent moisture damage prior to soldering. Validate that the specific suffix matches the required pinout and electrical characteristics for the target design.

Selection Notes

Select this component when a compact stereo CODEC with integrated headphone drive is required for battery-powered applications. Compare against the WM8753 if additional PCM codec capabilities or a different package size are needed. Consider the WM8758 for designs requiring higher DAC signal-to-noise ratios but accepting a narrower input voltage range. Ensure the system architecture supports the required serial interface protocol for configuration.
