概述
The LPA2101A is a 30W, class F mono audio amplifier integrated Class AB/D optional mode. It is capable of delivering 29watts of continuous average power to a 4Ω BTL load with less than 10% distortion (THD) from a 15V DC power supply. It offers low THD+N, allowing it to achieve high-quality Power Supply sound reproduction. The LPA2101A device is fully protected against faults with short-circuit protection and thermal protection. Faults are reported back to the processor to prevent devices form being damaged during overload conditions.
