The device also offers extended power supply range, making it an excellent choice for both automotive and consumer applications.
Working Principle
The TPA6139A2PWR works by amplifying a small input signal, usually from a microphone or other input device, and then sending the amplified audio signal out to a pair of audio speakers. The device basically consist of an input stage, a gain controller, an output buffer and an output stage, which are all interconnected to form a signal amplifier. The input stage of the amplifier is where the input signal is amplified and the gain controller sets the output level for the amplifier. The output buffer takes the signal from the output of the gain controller and before it is sent out to the output stage, where the signal is further amplified. The output stage then sends the amplified signal to the speakers.
Advantages
The main advantages of the TPA6139A2PWR amplifier include its low noise, low cost and excellent power efficiency, as well as its wide gain range and extended power supply range. Furthermore, the device does not require external components, making it easy to install and use. The TPA6139A2PWR is also capable of driving both high-impedance and low-impedance loads, making it suitable for various audio systems.
Conclusion
The TPA6139A2PWR is an ideal audio amplifier for applications where low-noise performance and power efficiency are critical. It offers excellent sound quality and has a wide gain range and extended power supply range, making it suitable for a variety of audio systems. And because it does not require external components, it is easy to install and use, making it a great option for audio systems in portable devices like tablets, laptops, and soundbars.
