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.
