Description

NCP2811 is a dual audio power amplifier designed for portable
communication device applications such as mobile phones. This board
showcases the A version of this part in the WQFN12 package. This
part is capable of delivering 27 mW of continuous average power into
a 16 W 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 to Ground. In this True Ground configuration, the two
external heavy coupling capacitors can be removed. It offers
significant space and cost savings compared to a typical stereo
application.
