LPA2101A
Filterless 30W Class F Mono Audio Amplifier With AGC function
概述
The LPA2110A is a 25W, class F mono audio amplifier integrated Class AB/D optional mode. It is capable of delivering 25watts of continuous average power to a 4Ω BTL load with less than 10% distortion (THD) from a 14.5V DC power supply. It offers low THD+N, allowing it to achieve high-quality Power Supply sound reproduction. The LPA2110A device is fully protected against faults with short-circuit protection and thermal protection as well as over-voltage and DC protection. Faults are reported back to the processor to prevent devices form being damaged during overload conditions.
