15W

WA15-6819B

The WA15-6819B is a single chip full digital audio amplifier including power stage for stereo amplifier system. WA15-6819B is integrated with versatile digital audio signal processing functions, high- performance, high-fidelity fully digital PWM modulator and 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 like 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.
