TPA032D03 具有立体声耳机驱动器的单声道中等功耗 D 类音频放大器

The TPA032D03 is a monolithic power IC mono audio amplifier that operates in extremely efficient Class-D operation, using the high switching speed of power DMOS transistors to replicate the analog input signal through high-frequency switching of the output stage. This allows the TPA032D03 to be configured as a bridge-tied load (BTL) amplifier capable of delivering up to 10 W of continuous average power into a 4- load at 0.5% THD+N from a 12-V power supply in the high-fidelity audio frequency range (20 Hz to 20 kHz). A BTL configuration eliminates the need for external coupling capacitors on the output. Included is a Class-AB headphone amplifier with interface logic to select between the two modes of operation. Only one amplifier is active at any given time, and the other is in power-saving sleep mode
