NCP2811AFCT1GEVB: Dual Audio Power Supply Evaluation Board

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 12-Pin Flip-Chip package. 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 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.
