The TPA731DG4 is a highly versatile audio signal linear amplifier and one of the most popular choices in the professional audio industry. It is used in a variety of systems and applications, from broadcast, AV, to home theater. The TPA731DG4 is a Class-D amplifier, meaning that it uses MOSFETs to drive the signal in a linear fashion, with very low power consumption and distortion. This makes it an ideal choice for applications, where high sound quality and low power consumption are required.

The TPA731DG4 features an extremely low noise floor, low distortion and high output power. The amplifier is capable of driving up to 4 ohm loads, and its 1.2kHz – 100kHz frequency response gives it a wide range of applications. It also supports pulse width modulation (PWM) and current-drive output functions, enabling a variety of sound quality adjustments.

The TPA731DG4 is a single-ended amplifier, meaning it has a single output for the input signal. It takes a low-level input signal, typically from an audio source such as a microphone or other audio device and amplifies it to a higher output level. The amplifier features a differential input stage, coupled with an output stage that converts the voltage-level signal into a current-level signal. This allows the amplifier to drive high-performance and low-power loudspeakers without running the risk of overloading the input stage.

The TPA731DG4 has a wide range of protections and safeguards designed to ensure that the amplifier always plays within its limits. It has thermal protection and short-circuit protection with automatic rest when necessary. It also includes a resistive load protection and DC protection, to help prevent damaged speakers and other audio equipment.

The TPA731DG4 is a high-power, low-distortion amplifier suitable for a variety of audio applications. It can be used in professional audio/video systems, home theater, as well as in car audio systems. Its high power, low noise, and wide frequency response make it an ideal choice for driving high-performance loudspeakers. Its low power consumption and economical design make it an attractive solution for the budget-minded consumer.
