The TPA6120A2RGYR is a class-AB audio power amplifier that is used as an output amplifier to drive both speakers and headphones. It is designed by Texas Instruments and it is the successor to the TPA6120A2. It is manufactured using BiCMOS technology, which combines the best properties of positive-channel CMOS and BiPolar technologies. The amplifier offers low distortion, low noise, and high power.

The audio power amplifier has an adjustable gain of 2.1 to 40 dB, with a low noise figure of 60 μV(rms) and input IP3 of +42 dBm. The maximum power output at 1.3V is 6 watts and the peak power output at 4.2 V is 8 watts. It supports both 8- and 16-ohm loads, with a closed-loop gain response from 0.8V/W to 3v/W. The device has a wide supply voltage range of 2.6v to 5.5V. The TPA6120A2RGYR can be used for both speakers and headphones, and is suitable for mobile applications such as smartphones and portable music players.

The device functions as an efficient class-AB amplifier. It has an input stage of a differential amplifier consisting of two N-channel MOSFETs, a Common-mode feedback circuit, and an input resistive network. The output stage consists of two NPN transistors connected in an emitter-follower configuration. This configuration ensures high output power with low distortion and noise. The output power capacity of the device is 6 watts and it provides a voltage gain of 2.1 to 40 dB. The TPA6120A2RGYR also has thermal protection that prevents the device from being damaged due to excessive heat.

The TPA6120A2RGYR power amplifier is ideal for mobile devices that require high power output, low noise and distortion, and low power consumption. It has a wide supply voltage range and adjustable gain, which are suitable for a variety of audio applications. Its low power consumption makes it ideal for battery-powered devices such as smartphones and portable music players. Its high power output and low distortion make it suitable for both speakers and headphones.
