TPA731DRG4

TPA731DRG4 is a product of Texas Instruments, a leader in the production of consumer and industrial electronics. Featuring audio performance and high power efficiency, TPA731DRG4 is ideal for audio, consumer or portable applications that require low-power operation. This amplifier operates at a low quiescent current of 2 mA while maintaining efficient output ratings up to 6 W with a signal−to−noise ratio of 97 dBA.

TPA731DRG4 is a dual-channel, audio amplifier designed for use in the audio, consumer and portable applications. The amplifier combines low-power consumption and high efficiency with Class D operation. It is capable of driving up to 6 watts of power per channel into an 8-ohm load with a signal to noise ratio of 97 dBA. Class D amplifiers have low power losses and high power densities, making them well suited for low-power applications such as portable electronics and consumer electronics.

The TPA731DRG4 integrates a pair of identical Class D amplifiers on a single chip. Each amplifier is capable of driving up to 6 W of output power into an 8-ohm load. When operated in stereo mode, each amplifier will be connected to one of the two output channels. The amplifier also features built-in protection circuitry against output-current overload, excessive output offset, and thermal overloads.

The design of the amplifier has been optimized for distortion performance. The inputs are internally well-matched to reduce distortion and the device is designed to provide minimal variation in the output level with varying input levels (A-weighted). In addition, the TPA731DRG4 featuring THD (total harmonic distortion) ratings of 0.02%.

The TPA731DRG4 features high input impedance and has low output impedance that provides a high dynamic range and a low noise floor. It also features wide-band operation and fast settling times in order to provide a clean sound. The amplifier is also compatible with a wide range of digital audio formats such as PCM, MP3, WMA, FLAC and AAC.

The TPA731DRG4 is ideal for applications such as portable audio players, portable music systems and multimedia applications. It provides high-quality audio performance and flexible design options for developers looking for a low-power, high-efficiency audio amplifier. Its low power consumption and Class D operation make it an ideal choice for mobile applications.
