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 provid.
