Pin Pin Name Type Description A1 CPM Input / Output Charge pump flying capacitor negative terminal. A 1 mF ceramic filtering capacitor to CPP is required A2 PVM A3 INL Output Input Charge pump output. A 1 mF ceramic filtering capacitor to ground is required Left input of the audio source A.

NCP2815 NOCAPt LongPlay Headphone Amplifier NCP2815 is a dual LongPlay true ground headphone amplifier designed for portable communication device applications such as mobile phones. This part is capable of delivering 26 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 output.
