Working Principles

The TPA2010D1YZFT is a class-D audio amplifier that utilizes pulse-width modulation (PWM) to convert the input audio signal into a high-frequency square wave. This square wave is then filtered and amplified to drive the connected speaker.

The amplifier operates by rapidly switching the output stage between two states: on and off. This switching action minimizes power dissipation, resulting in high efficiency. The AGC feature ensures consistent audio levels even when the input signal varies.

Detailed Application Field Plans

The TPA2010D1YZFT is widely used in portable electronic devices that require audio amplification, such as:

1. Smartphones and tablets
2. Portable media players
3. Bluetooth speakers
4. Gaming consoles
5. Wearable devices
