Description:

The Product is a high-performance Class D power amplifier with high efficiency and high-end sound quality.

The major advantage of a class-D amplifier is that it can be more efficient than a linear amplifier, with less power dissipated as heat in the active devices. Given that large heat sinks are not required, Class-D amplifiers are much weight than analog amplifiers.

The device features an advanced integrated feedback design and proprietary high-speed gate driver with error correction. This technology allows the device to maintain an ultra-low distortion throughout the audio band while delivering the perfect sound quality.

The device(with unclipped power) can drive up to two 315W/4R loads and two 150W/8R loads when operates in AD mode and THD of 10%. and it features a 2 VRMS analog input interface for high-performance DACs with Seamless connection (for like TI PCM5242).

In addition to outstanding audio performance, the product combines high power efficiency with ultra-low power stage idle loss (less than 2.5W). This can be achieved with an 85mR MOSFET and an optimized gate driver solution. This solution can significantly reduce idle losses compared to traditional discrete implementations.
