The TPA3111D1EVM is an evaluation module for TPA3111D1 10W efficient, Class-D audio power amplifier. complete with a small number of external components mounted on a circuit board that can be used to directly drive a speaker with an external analog audio source as the input. The evaluation modules default output filter configuration supports filter free operation, but can easily be configured to support LC filter operation, but can easily be configured to support filter free operation. Designers can quickly evaluate the sound quality and verify specifications in their application with the TPA3111D1EVM. The TPA3111D1 can drive a mono speaker as low as 4R. The high efficiency of the TPA3111D1, greater then 90%, eliminates the need for an external heat sink when playing music. Advanced EMI Suppression technology enables the use of inexpensive ferrite bead filters at the outputs while meeting EMC requirements.
Greater Then 90% efficient Class-D operation
Support for filter free operation
Speaker guard speaker protection circuitry
Four selectable, fixed gain settings
8V to 26V wide operating voltage
Thermal and short circuit protection with auto recovery feature
Its important to operate this EVM within the input voltage range of -0.3V to 6.3V and the output voltage range of -0.3V to 30V.Exceeding the specified input voltage range may cause damage to the EVM.
