GEN E RA L DESCR I PTION

The TDA1400 is a one-channel, Amplifier Driver that uses Tripath’s proprietary Digital Power Processing

(DPP

chipsets while providing exceptional audio performance for real world applications. Class-T amplifiers

offer both the audio fidelity of Class-AB and the power efficiency of Class-D amplifiers.

The TDA1400 is typically configured as a single supply, bridged output. This makes the power supply

requirements simpler and maximizes the output power for a given voltage rail. Additionally, the TDA1400

can be configured as a split supply, bridged amplifier, with the addition of some external components. The

TDA1400 is capable of full range operation but the target application is subwoofers due to the high output

power capability and single channel operation.
