The TPA6404QDKQRQ1’s working principle can be broken down into three stages - the input stage, the amplifier stage, and the output stage. At the input stage, the differential input signal is compared to the reference voltage level before passing it to the amplifier stage. In the amplifier stage, the differential input is amplified and then passed to the output stage. At the output stage, the amplified differential signal is converted into a single-ended and inverted output signal by the P-type differential MOSFET transistors. This single-ended and inverted output signal is then passed to an audio system.

In conclusion, the TPA6404QDKQRQ1 is a digitally-controlled audio amplifier with excellent performance in terms of low power consumption, audio quality, and wide dynamic range. The device features a current-feedback amplifier architecture with a differential input stage and a P-type differential MOSFET output stage, allowing for user-defined digital processing of audio signals. The amplifier also includes a protection circuit to protect from over-voltage, over-current, and other fault conditions. The TPA6404QDKQRQ1 is suitable for a wide range of audio applications, from home and car audio systems to portable entertainment devices.
