The TPA6017A2PWPR is a fully integrated audio power amplifier from Texas Instruments. A modern class of linear audio power amplifiers, the TPA6017A2PWPR combines an advanced process technology, low external component count, and high supply voltage into a power amplifier design that provides superior loudness and signal fidelity from any input source.

The most noteworthy feature of the TPA6017A2PWPR is its Class-G topology, which enables it to provide industry-leading loudness and signal fidelity while using less power and taking up less real estate. Class-G amplifiers use a two-stage power amplifier and two power supply rails: a low-voltage rail and a high-voltage rail. The amplifier automatically switches between the two rails as the output load changes, driving the signal into its maximum level without sacrificing quality or power consumption.

In addition to its Class-G technology, the TPA6017A2PWPR utilizes a proprietary overdrive control technology. This overdrive control automatically detects signal peaks, saturates the signal before clipping, and prevents other artifacts such as phase shift or crossover distortion. This technology allows the amplifier to deliver a higher signal fidelity with less distortion and background noise.

The TPA6017A2PWPR is designed to conform to the industry standard I2C Audio Bus and to support both mono and stereo operation. The amplifier also features programmable gain, a low power standby mode, and is compatible with a wide range of digital inputs such as USB, SPDIF, and Bluetooth. This makes it an ideal choice for multiple applications such as home theaters, computer speakers, portable audio devices, and automotive audio systems.

In terms of its working principle, the TPA6017A2PWPR follows a standard differential-input class AB amplifier design. It comprises two output power transistors that are driven by differential inputs in a push-pull configuration. Each output is connected to a power supply rail, and the low rail supplies power to the quiescent current of the transistors, while the high rail provides the necessary voltage boost for the transistors to drive the high dynamic range. This design optimizes total harmonic distortion, output power, and efficiency of the amplifier, resulting in improved sound performance.

In summary, the TPA6017A2PWPR is an advanced linear audio power amplifier designed by Texas Instruments and is classified as a class-G amplifier. It is a fully integrated audio power amplifier featuring an I2C audio bus, programmable gain, a low-power standby mode, and compatibility with digital inputs. Additionally, it utilizes a two-stage differential-input Class AB amplifier design and a proprietary overdrive control technology to achieve superior loudness and signal fidelity. This makes it an ideal solution for a wide range of applications.
