Product Specification

The WA20-5822 is a single chip full digital audio amplifier including power stage for stereo amplifier system. WA20-5822 is integrated with versatile digital audio signal processing functions, high-performance, high fidelity fully digital PWM modulator and two high-power full-bridge MOSFET power stages.
The WA20-5822 receives digital serial audio data with sampling frequencies of 32kHz, 44.1kHz, 48kHz, and 96kHz. It delivers 2 x 20 watts in stereo mode without heat sink.
The WA20-5822 has a mixer and Bi-Quad filters which can be used to implement the essential audio signal processing functions such as loudness control, compensation of a loudspeaker response and parametric equalization.
All the functions of the WA20-5822 can be controlled by internal register values via I2C host interface bus.
