Overview
The WM8962BECSN/R is a low-power stereo CODEC designed for portable digital audio applications. It integrates Class D speaker drivers delivering 2W per channel into 4Ω BTL loads at 5V, and ground-referenced headphone drivers using Wolfson 'Class-W' technology to eliminate DC-blocking capacitors. The device features two stereo 24-bit sigma-delta ADCs and DACs with SNR ratings of 94dB and 98dB respectively at 1.8V. An integrated programmable DSP provides audio enhancement algorithms including Virtual Surround Sound, HD Bass, and ReTune™. It operates on analogue supplies from 1.7V to 2.0V, digital supplies down to 1.62V, and supports sample rates from 8kHz to 96kHz.
Feature Summary
- Integrated Class D speaker drivers and ground-referenced headphone outputs remove the need for external coupling capacitors.
- Programmable audio enhancement DSP includes preset algorithms such as Virtual Surround Sound, HD Bass, and ReTune™.
- Flexible input configuration supports four stereo or eight mono inputs, accommodating both analogue and digital microphone interfaces.
- SilentSwitch™ technology utilizes a control sequencer to minimize pops and clicks during power-up and power-down sequences.
Applications
- Portable gaming devices
- Mobile multimedia systems
- Voice recorders
- Stereo digital still camera camcorders
Procurement Notes
Verify the specific ordering code WM8962BECSN/R against manufacturer documentation to confirm package type and moisture sensitivity level. Ensure compatibility with required temperature ranges and soldering profiles before procurement. Confirm that the reel quantity matches system requirements.
Selection Notes
Select this component when an ultra-low power stereo CODEC with integrated Class D amplification is required. It is suitable for designs needing ground-referenced headphone outputs without external DC-blocking capacitors. Consider its integrated DSP capabilities if audio enhancement features like Virtual Surround Sound are necessary.
Part Context
The WM8962B belongs to Cirrus Logic's line of high-performance audio CODECs optimized for portable electronics. This specific model variant is packaged in a 49-ball W-CSP (3.6x3.9mm), making it ideal for space-constrained handheld and portable systems where board real estate is limited.
Replacement Considerations
Consult official datasheets for direct pin-compatible alternatives within the same product family. Verify electrical characteristics and software register compatibility before substituting any other audio CODEC models.
