Description:
8571 is a 5W mono high efficiency class AB/D audio power amplifier. It can provide 5W output power to 2Ω 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.
Features:
1. Output power:
PO at 10%THD+N, VDD=5V, RL=4Ω 3.12W (typical value)
RL=2Ω 5W (typical value)
PO at 10%THD+N, VDD=3.7V, RL=4Ω 1.77W (typical value)
RL=2Ω 2.63W (typical value)
2. No need for heat sink, efficiency up to 90%
3. Large power supply voltage range: 2.5~5.5V
4.Unique AERC technology provides excellent full-bandwidth EMI suppression
5.Excellent low noise suppression function
6.Class-D structure without wave filtering
7.Fast start-up time: 150ms
8.Low quiescent current: 5mA
9.Low shutdown current: <0.1uA
10.Overcurrent protection, short circuit protection, overheating protection
