Working Principle

The TPA3136D2PWPR is a fully-differential, high-efficiency amplifier IC. The input signal is first converted from analog form to digital form, via an internal ADC, and then passed to the output stage. The output stage consists of a pair of power MOSFETs, configured as Class-D amplifiers.

The two power MOSFETs are configured as two parallel push-pull amplifiers. The input signals are then fed to the gates of the MOSFETs, and their outputs are combined in an output stage. The output stage uses a pair of low-pass LC filters to remove any high frequency components from the signal, before the output is passed to the speaker.

The TPA3136D2PWPR also includes a DC offset cancellation circuit, which allows the amplifier to operate without any signal clipping or distortion. This ensures that the sound quality remains distortion-free, even at high output volumes.

Overall, the TPA3136D2PWPR provides a high performance, low-noise amplifier, with excellent efficiency and sound quality. It is a highly integrated device that can be used in a variety of audio applications, including portable and device audio, as well as automotive audio applications.
