LPSemi/微源半导体 LPA2101A ESOP-8 无滤波器30W F类单声道音频放大器，带AGC功能

General Description

The LPA2101A is a 30W, class F mono audio amplifierintegrated Class AB/D optional mode. It is capable ofdelivering 29watts of continuous average power to a4Ω BTL load with less than 10% distortion (THD) froma 15V DC power supply. It offers low THD+N, allowingit to achieve high-quality Power Supply soundreproduction. The LPA2101A device is fully protectedagainst faults with short-circuit protection and thermalprotection. Faults are reported back to the processorto prevent devices form being damaged duringoverload conditions.
