TPA2014D1: Low Voltage Class-D Audio Power Amplifier for ...

https://freecircuitdiagram.com/517-tpa2014d1-low-voltage-class-d-audio-power-amplifier-for-portable-devices/

Here is the schematic diagram of the circuit: The amplifier’s PWM and the supply booster PWM is internaly synchronized, thus eliminating beat frequency noises from the PWM stage. The gain control pin can be pulled to Vcc, floated, or grounded to set the gain to 2V/V, 6V/V, or 10V/V. The input stage of this class-D amplifier chip has internal low-pas filter to ensure the anti-aliasing …
