WM8988LGECN/RV

Overview

The WM8988LGECN/RV is a stereo audio CODEC manufactured by Cirrus Logic Inc., designed for portable audio applications. It integrates two ADCs and two DACs with 24-bit resolution, supporting sampling rates up to 96 kHz. The device operates on analog supply voltages from 1.8 V to 3.6 V and digital supply voltages from 1.42 V to 3.6 V. It features a typical SNR of 93 dB for the ADC and 100 dB for the DAC. The component is housed in a 28-QFN (4x4 mm) package, suitable for surface mount installation, and functions within an operating temperature range of -25°C to +85°C.

Feature Summary

Integrates high-performance stereo ADC and DAC converters with 24-bit resolution for precise audio signal processing.
Supports multiple serial interface formats including I2S, left-justified, and right-justified modes for flexible system integration.
Includes programmable gain amplifiers and output drivers capable of powering headphones and speakers directly.

Applications

Portable audio devices such as MP3 players and digital voice recorders
Embedded systems requiring low-power stereo audio input and output
Professional audio interfaces and sound cards

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 manufacturing updates affecting pinout or electrical characteristics before finalizing procurement plans.

Selection Notes

Select this component when a stereo CODEC with integrated headphone and speaker drivers is required for space-constrained designs. Ensure the host processor supports the necessary serial interface protocols and voltage levels. Consider the 28-QFN package dimensions and thermal performance relative to the application environment.
