The TPA032D04 is a monolithic power IC stereo 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 TPA032D04 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.
