15-W MONO CLASS-D AUDIO POWER AMPLIFIER

General Description

The TMPA401DM is a bridged-tied (BTL) Class-D audio amplifier for driving speakers with high power efficiency. It can drive 4Ω, 6Ω, 8Ω or 16Ω speakers. The output power can be up to 15W. No external heat-sink is necessary. The gain of the amplifier is defined by input resistance. The internally fully differential input structure provides good common mode rejection and power supply rejection. Thermal protection and short-circuit protection are integrated for safety purpose. The internal de-pop circuitry eliminates pop noise at power-up & shutdown operations.

Description

The TDA1400 is a one-channel, Amplifier Driver that uses Tripath’s proprietary Digital Power Processing  (DPPTM) technology. The TDA1400 offers higher integration over previous Tripath amplifiers driver  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.
