The TPA005D12 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 TPA005D12 to be configured as a bridge-tied load (BTL) amplifier capable of delivering up to 2 W of continuous average power into a 4- load at 0.5% THD+N NC No internal connection
