微源 LPA2110 D类单声道音频放大器

General Description

The LPA2110 is a 30W, class D mono audio amplifier. 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 LPA2110 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.
