Codecs datasheet and documents for WM8974CGEFL/V

WM8974CGEFL/V

Codecs Overview

The WM8974CGEFL/V is a mono audio CODEC designed for portable applications, integrating high-quality digital-to-analog and analog-to-digital conversion with integrated speaker and headphone drivers. It operates on supply voltages from 2.5V to 3.6V, with digital supplies down to 1.71V. The device supports sample rates from 8kHz to 48kHz with 24-bit resolution. Key electrical specifications include a DAC signal-to-noise ratio of 98dB and an ADC SNR of 94dB. It features a BTL speaker driver capable of 0.9W into 8Ω at 5V and a headphone output of 40mW into 16Ω. The component is housed in a 24-lead QFN package measuring 4x4mm.

Codecs Feature Summary

Integrates mono DAC and ADC with built-in speaker and headphone drivers, reducing external component requirements.
Includes programmable microphone preamplifiers with automatic level control and noise gate functionality.
Features advanced digital signal processing including a 5-band equalizer, digital limiter, and wind noise reduction filters.
Supports flexible digital audio interfaces (I2S/PCM) and includes an on-chip PLL for clock generation.

Codecs Applications

Digital still camera audio codecs
Wireless VoIP headsets and communication handsets
Portable audio recorders

Codecs Procurement Notes

Verify the specific ordering suffix 'V' against manufacturer documentation to confirm tape and reel packaging status versus cut tape availability. Confirm current production lifecycle status as components may be subject to end-of-life notifications or obsolescence. Ensure moisture sensitivity level MSL3 handling protocols are followed during storage and assembly processes.

Codecs Selection Notes

Select this component for mono audio applications requiring integrated amplification to minimize board space. Verify that the required power supply rails align with the 2.5V to 3.6V analog range and 1.71V digital core requirement. Ensure the host processor supports either the 2-wire or 3-wire serial control interface for register configuration.

Codecs Part Context

The WM8974 belongs to Cirrus Logic's low-power audio codec family, specifically tailored for portable devices. It serves as a cost-effective solution for mono audio paths where stereo capability is unnecessary. The integration of both ADC and DAC with output drivers distinguishes it from simpler converter-only ICs, offering a complete audio front-end solution.
