NCP2811 NOCAPt Advanced Stereo Headphone Amplifier NCP2811 is a dual audio power amplifier designed for portable communication device applications such as mobile phones.
This part is capable of delivering 27 mW of continuous average power into a 16 Ω load from a 2.7 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
