NCP2811ADTBRGEVB: Dual Audio Power Evaluation Board
Evaluation Board 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 TSSOP-14 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.
