Product Description

General Description：


The WA15-6819B is a single chip full digital audio amplifier including power stage for stereo amplifier system. The WA15-6819B 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 WA15-6819B receives digital serial audio data with sampling frequencies of 32kHz, 44.1kHz, 48kHz, and 96kHz. It delivers 2 x 15 watts in stereo mode without heat sink.



The WA15-6819B 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 loud speaker response and parametric equalization.


All the functions of the WA15-6819B can be controlled by internal register values via I2C host interface bus.
