Description
8571 is a 5W mono high efficiency class AB/D audio power amplifier. It can provide 5W output power to 2┯ load under 5V power supply, and has an efficiency of up to 90%.
8571 adopts the proprietary AERC (Adaptive Edge Rate Contrl) technology, which greatly reduces EMI interference within the full audio bandwidth range. For 60cm audio lines, it has a margin of more than 20dB under the FCC standard.
The 8571 has built-in overcurrent protection, undervoltage protection, and overheating protection functions, which effectively protect the chip from damage under abnormal working conditions.
