NCP2817 NOCAP] LongPlay Headphone Amplifier NCP2817 is a dual LongPlay true ground headphone amplifier designed for portable communication device applications such as mobile phones. This part is capable of delivering typical 27 mW of continuous average power into a 32 W load from a 1.8 V power supply with a THD+N of 1%. Based on the power supply delivered to the device, an internal power management block generates a symmetrical positive and negative voltage. Thus, the internal amplifiers provide outputs referenced to Ground and the losses are reduced which helps to increase the battery life. In this NOCAP configuration, the two external heavy coupling capacitors can be removed. It offers significant space and cost savings compared to a typical stereo application.
