WM8960 Low Power, Stereo Codec with Class D Speaker Drivers
Cirrus Logic’s WM8960 features high-efficiency Class D speaker drivers to provide 1 W per channel into 8 Ω speakers
Cirrus Logic's WM8960 is a low power stereo codec featuring Class D speaker drivers to provide 1 W per channel into 8 W loads. Guaranteed low leakage, excellent PSRR, and pop/click suppression mechanisms enable direct battery connection for the speaker supply. This IC integrates a complete microphone interface and a stereo headphone driver. External component requirements are drastically reduced as no separate microphone, speaker, or headphone amplifiers are required. Advanced on-chip digital signal processing performs automatic level control for the microphone or line input. Stereo 24-bit delta-sigma converters are used with low power over-sampling digital interpolation and decimation filters and a flexible digital audio interface. The master clock can be input directly or generated internally by an onboard PLL supporting most commonly used clocking schemes.
Block Diagram
- High fidelity stereo audio with high speaker power output
- High efficiency stereo class D speaker drivers deliver 1 W per channel into 8 Ω speakers from a 5 V supply
- The 24-bit stereo ADCs and DACs use Cirrus Logic's audio architecture providing high performance at very low power
- Stereo headphone and line drivers with full analog volume control are integrated with headphone detection support
- A complete stereo differential microphone interface provides high gain and low noise recording at hi-fi quality
- Integrated headphone detection jack
- Removes the requirements for external jack detect component
- Supports capless mode for headphone
- OUT3 mono mixer configurable as mono output or virtual Vmid out
- Integrated PLL
- The master clock can be input directly or generated internally by an onboard PLL, supporting most commonly-used clocking schemes
- Reduces external component count
- Low leakage, high PSRR, anti-pop mechanisms, and flexible signal boosting also enable direct battery connection, reducing external components, and minimizing power consumption
- External component requirements are drastically reduced as no separate microphone, speaker, or headphone amplifiers are required
- Advanced on-chip digital signal processing performs automatic level control for the microphone or line input
- Extends battery life in active, standby, and off modes
- The WM8960 operates at analog supply voltages down to 2.7 V, although the digital core can operate at voltages down to 1.71 V to save power
- The speaker supply can operate at up to 5.5 V, providing >1 W per channel into an 8 Ω load
- For power optimization, sections of the chip can be powered down under software control
