ON Semiconductor NCP2990FCT2G Audio Amplifier

The NCP2990FCT2G from ON Semiconductor is a high-quality audio amplifier designed for portable communication devices. It is a perfect solution for applications requiring a low-power, low-voltage audio amplification with superior sound quality. The device is capable of delivering 1.4W of continuous average power to an 8 Ohm BTL load with less than 1% distortion (THD+N) from a 5V power supply, making it an excellent choice for mobile phones, tablets, and other personal electronic devices.

This audio amplifier integrates a unique, fully differential amplifier design that significantly reduces RF rectification effects, thus providing an improved signal-to-noise ratio and enhancing the overall audio experience. The NCP2990FCT2G also features a built-in thermal shutdown mechanism, which protects the device from overheating, ensuring reliable operation and longevity.

With its low quiescent current and superior efficiency, the NCP2990FCT2G is optimized for battery-powered devices where power conservation is critical. The amplifier operates over a wide supply voltage range from 2.2V to 5.5V, which makes it flexible for use in various system designs. Additionally, the NCP2990FCT2G is designed with a "pop & click" noise suppression circuitry that minimizes noise typically heard during turn-on and turn-off transitions.

The NCP2990FCT2G comes in a compact, surface-mount package, which is ideal for space-constrained applications. Its lead-free and RoHS-compliant design aligns with environmental standards, making it a suitable choice for eco-friendly product designs.
