Overview
The WM8960CGEFL/V is a low-power stereo CODEC designed for portable digital audio applications. It integrates stereo Class-D speaker drivers capable of delivering 1W per channel into 8Ω loads with a 5V supply, alongside headphone drivers. The device features 24-bit sigma-delta ADCs and DACs with flexible digital audio interfaces. Key electrical specifications include a DAC SNR of 98dB (A-weighted) and THD of -84dB at 48kHz with a 3.3V supply. The ADC provides an SNR of 94dB (A-weighted) and THD of -82dB under the same conditions. Operating voltages range from 2.7V to 3.6V for analogue supplies, 1.71V to 3.6V for digital core/buffer supplies, and up to 5.5V for speaker supplies. It is housed in a 32-lead QFN package measuring 5x5x0.9mm.
Feature Summary
- Integrated stereo Class-D speaker drivers and headphone drivers eliminate the need for external amplifiers.
- Advanced on-chip digital signal processing includes automatic level control, 3D enhancement, and pop/click suppression mechanisms.
- Flexible input configuration supports up to three stereo sources and includes a complete microphone interface with programmable gain amplifiers.
- Internal PLL generates required audio clocks from common reference frequencies, supporting master or slave digital audio interface modes.
Applications
- Portable digital audio systems
- Hand-held multimedia devices
- Digital cameras and camcorders
Procurement Notes
Verify the ordering suffix 'V' indicates tray packaging when sourcing this component. Confirm the moisture sensitivity level is MSL3 and the peak soldering temperature rating is 260°C. Ensure the supplier documentation matches the Cirrus Logic datasheet revision 4.4 dated January 2019 for accurate pinout and electrical characteristics.
Selection Notes
Select this component for designs requiring integrated speaker and headphone driving capabilities within a compact form factor. Verify that the application can support the specified voltage ranges for analogue, digital, and speaker supplies. Consider the thermal performance given the QFN package size and the power dissipation characteristics listed in the typical power consumption tables.
Part Context
The WM8960 belongs to Cirrus Logic's line of high-quality stereo CODECs optimized for portable electronics. It distinguishes itself by combining high-fidelity audio conversion with substantial output drive capability in a single small package. This integration reduces the bill of materials and board space compared to solutions requiring separate codec and amplifier ICs.
Replacement Considerations
The WM8960CGEFL/RV is the tape-and-reel version of the same device. Cross-model replacements require careful evaluation of pin compatibility, power supply requirements, and audio performance metrics against the original design specifications.
