The AU6815 is a digital-input, dual-channel stereo, high-efficiency Class D audio power amplifier with a maximum output power of up to 2 × 25W or 1 × 50W, and an operating voltage range of 4.5V to 21V. It employs an innovative modulation mode to effectively reduce static power consumption and enhance battery life. The AU6815 integrates a 32-bit high-precision audio DSP, which provides tuning algorithms including 2 × 15-band equalizers, 3-band DRC, and AGL. Additionally, to enhance bass performance at low volumes, the AU6815 supports the Dynamic Bass Enhancement Algorithm (DPEQ). The internal DSP of the AU6815 supports a maximum processing bandwidth of 96kHz (with a sampling rate of 192kHz).In terms of audio performance, the AU6815 achieves a THD+N level of less than 0.03%. Its extremely low DC offset voltage also ensures outstanding performance in eliminating pop noise during power-on and power-off. As a medium to high-power audio amplifier, the AU6815 supports four levels of over-temperature alarms and over-temperature shutdown protection. The chip temperature can be continuously output via registers, facilitating overall system thermal management. For speaker protection, the AU6815 also supports overcurrent, overvoltage, undervoltage, and DC protection.The AU6815 is available in a TSSOP-28 package without the need for a heatsink, and its rated operating temperature range is from -40°C to +85°C.
