WM8988LGECN/V

Overview

The WM8988LGECN/V is a stereo audio codec designed for portable applications, manufactured by Cirrus Logic Inc. It integrates two analog-to-digital converters and two digital-to-analog converters with 24-bit resolution. The device supports a sampling rate of up to 96 kHz and operates within an analog supply voltage range of 1.8V to 3.6V and a digital supply voltage range of 1.42V to 3.6V. Typical signal-to-noise ratios are 93 dB for the ADC and 100 dB for the DAC. It utilizes a 28-pin UFQFN package (4x4 mm) and functions within a temperature range of -25°C to +85°C.

Feature Summary

Integrates high-performance stereo ADC and DAC channels for portable audio processing
Supports multiple serial audio interface formats including I2S, left-justified, and right-justified modes
Includes integrated headphone drivers and microphone bias supplies for system simplification

Applications

Portable media players and MP3 devices
Smartphones and mobile communication handsets
Digital voice recorders and dictaphones

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm RoHS compliance and moisture sensitivity level (MSL 3) requirements during storage and handling. Review Product Change Notices (PCN) for any packaging or labeling updates issued prior to discontinuation.

Selection Notes

Select this component for designs requiring low-power stereo conversion in compact form factors. Ensure the host processor supports the required serial interface protocols and I2C configuration lines. Validate power supply constraints against the specified analog and digital voltage ranges to maintain optimal performance metrics.

Part Context

This part belongs to the WM8988 series of stereo CODECs originally developed by Wolfson Microelectronics before its acquisition by Cirrus Logic. The suffix LGECN/V denotes specific package and environmental variants within the standard WM8988 family, sharing core functional specifications with other revisions like the RV variant.
