WM8532CGEFL/V

Overview

The WM8532CGEFL/V is a stereo digital-to-analog converter featuring an integral charge pump for selectable 1V RMS or 2V RMS ground-referenced line outputs from a single 3.3V supply. It supports audio sampling rates from 8kHz to 192kHz with a slave-mode interface compatible with Left Justified and I2S formats. Key performance metrics include a 106dB A-weighted SNR, -87dB THD, and 120dB mute attenuation. The device incorporates a DC servo to eliminate coupling capacitors and suppress power-on pops. It operates within a temperature range of -40°C to +85°C in a 24-lead QFN package.

Feature Summary

• High-performance stereo DAC with 106dB SNR (A-weighted) and -87dB THD
• Integrated charge pump enabling selectable 1V RMS or 2V RMS line driver outputs
• Hardware control interface supporting 24-bit Left Justified and I2S data formats
• DC servo eliminates external coupling capacitors and minimizes DC offset to ±1mV

Applications

• Games Consoles
• Set Top Box
• A/V Receivers
• DVD Players
• Digital TV

Procurement Notes

Verify the ordering suffix 'V' indicates tape and reel packaging when required, as the datasheet lists 'RV' explicitly for tape and reel while 'V' typically denotes cut tape. Confirm the component is the Wolfson Microelectronics version, as Cirrus Logic acquired Wolfson's assets. Ensure the specific revision history regarding copper wire bonding (Rev 4.1) aligns with manufacturing requirements.

Selection Notes

Select this component for applications requiring high-fidelity audio output without external coupling capacitors. The hardware control mode simplifies integration by removing the need for complex serial configuration registers. Ensure the system clock (MCLK) meets the jitter specifications to maintain optimal SNR. Verify that the DBVDD logic level compatibility matches the host processor's output voltage.

Part Context

The WM8532 is manufactured by Wolfson Microelectronics plc, which was acquired by Cirrus Logic. The datasheet revision history notes a transition to copper wire bonding in Rev 4.1, updating the order code from GEFL to CGEFL. This part belongs to the Wolfson stereo DAC family designed for consumer electronics requiring ground-referenced outputs.
