The AU6815P is a digital-input, dual-channel stereo, high-efficiency Class D audio power amplifier with a maximum output power of up to 2×32W in stereo mode or 1×60W in mono mode. It operates within a voltage range of 4.5V to 26.4V. The AU6815P employs an innovative modulation mode that effectively reduces quiescent power consumption, thereby extending playback time.Integrated within the AU6815P is a 32-bit high-precision audio DSP, which provides extensive audio tuning algorithms, including 2×15 equalizers, 3-band dynamic range compression (DRC), and Automatic Gain Leveler (AGL). Additionally, to enhance bass performance at low volumes, the AU6815P supports Dynamic Parametric EQ (DPEQ) for dynamic bass enhancement. The internal DSP of the AU6815P supports a processing bandwidth of up to 96kHz (with a 192kHz sampling rate).In terms of audio performance, the AU6815P achieves a Total Harmonic Distortion plus Noise (THD+N) level below 0.03%. Its extremely low DC offset voltage ensures excellent performance in minimizing pop noise during power-on and power-off.As a mid-to-high-power audio amplifier, the AU6815P offers four levels of over-temperature alarm and over-temperature shutdown protection for thermal management. The chip temperature can be continuously monitored via register output, facilitating overall system thermal management. For speaker protection, the AU6815P supports overcurrent, overvoltage, undervoltage, and DC protection.The AU6815P is available in a TSSOP-28 package without the need for a heatsink, and its operating temperature range is from -40°C to +85°C.
