WONDOM AB32231

Amplifier module TPA3110 Class D 2x8W 4 Ohm

Wondom AB32231 Module amplificateur TPA3110 Class D 2x8W 4 Ohm

A compact but really complete module

This small Class D AB32231 amplifier module from Wondom is based on a TPA3110 amplifier chip. It is capable of operating in stereo mode by delivering 2x8W and in mono mode by delivering 1x16W.

The compactness of this module and the power offered will allow you to create small, high-performance on-board systems. In addition, it offers many features and modes of use, allowing it to adapt to the great majority; needs (find explanations in sections "Mode and input method", "Mode Stéo" and "Mono Mode" on this page).

Wondom AB32231 TPA3110

TPA3110, a high-performance chip ideal for small systems

The TPA3110D2 amplifier chip from TI integrated in this AB32231 is ideal for designing small amplifiers. Indeed, this one makes it possible to deliver a sufficient power for this type of use and in a clean way. It uses an advanced EMI interference suppression system to limit noise interference.

In addition, this chip is capable of combining with stereo speakers with impedance down to 4 Ohm. Its high efficiency allows it to do without a heatsink and thus save space.
