TPA751D is a cost-effective audio power amplifier designed for commercial and consumer audio applications. It operates from a single supply and can drive up to 8 ohm loads. This linear amplifier can provide an output power of up to 10W into 8 ohm loads as well as a high-efficiency operation that reaches up to 93%.

The TPA751D is a current-feedback amplifier that is operated from a single supply between a 4.5V to 18V DC range. The feedback system ensures excellent load balance performance and dynamic behavior. Its wide bandwidth, low noise and distortion specifications make it suitable for portable audio systems, consumer and commercial audio applications. The TPA751D amplifier\'s unity-gain stable architecture enables it to be used as either a standalone amplifier or in a complex system.

The TPA751D employs a differential input stage with a Class AB topology. It has a gain programmable gain of up to 10V/V, which can be adjusted through a single external resistor. It includes a current-feedback output stage, which provides a high slew rate that ensures clean and precise transient response. The output stage also incorporates a thermal protection system that limits the output power when activated, as well as a short-circuit protection system that automatically resets when the fault condition is removed.

The TPA751D amplifier also features low supply-current consumption, optimized for power-efficient designs, and a precise gain temperature tracking system that regulates the amplifier\'s gain across its lifetime. Additionally, its comprehensive protection circuitry guard against undesired over-current, thermal and short-circuit conditions.

The TPA751D audio power amplifier is widely used in commercial and consumer audio applications such as portable audio systems, automotive systems, multimedia and laptop computers. Its flexibility and features makes it suitable for a variety of audio applications, such as speaker drives, Bluetooth and Wi-Fi speakers, subwoofers and multimedia soundbars. Additionally, it is also suitable for applications in medical instruments, data acquisition systems, test and measurement equipment and POS systems.
