WM8983GEFL/RV

Overview

The WM8983GEFL/RV is a stereo multimedia audio codec manufactured by Cirrus Logic, designed for portable digital devices. It integrates two analog-to-digital converters (ADCs) and two digital-to-analog converters (DACs) with a resolution of 24 bits. The device supports serial interfaces including 2-Wire and 3-Wire protocols. It operates within a power supply voltage range of 2.5 V to 3.6 V. The component features a signal-to-noise ratio of 95 dB for the ADC and 98 dB for the DAC. It functions at a conversion rate of 48 kHz and operates within a temperature range of -25°C to +85°C. The unit is housed in a QFN-32 package.

Procurement Notes

This component is listed as obsolete or end-of-life by the manufacturer. Verification of current availability through authorized distributors is required, as stock may be limited or unavailable. Sourcing should focus on verified surplus suppliers or qualified replacement alternatives that meet the original electrical specifications and pinout requirements.

Selection Notes

Engineers selecting this part must account for its discontinued status when designing new products. The QFN-32 package dimensions and thermal characteristics should be reviewed against PCB layout constraints. Compatibility with host processors using 2-Wire or 3-Wire serial interfaces must be confirmed prior to integration into the system architecture.

Part Context

The WM8983 belongs to Cirrus Logic's multimedia codec family, which combines audio conversion with power amplification capabilities. This specific model targets applications requiring integrated speaker driving solutions. It serves as a specialized solution for compact electronic devices where space efficiency and audio quality are critical design parameters.

Replacement Considerations

Potential substitutes include the WM8978 series or other Cirrus Logic codecs with similar QFN-32 footprints and integrated amplifier features. Cross-referencing datasheets for pin compatibility and electrical performance is essential before implementation.
