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.
