PCB Layout Information
package it gives all the advantages of a Class-D audio
amplifier. The required application board is focused on low
cost solution too. Due to its fully differential capability, the
audio signal can only be provided by an input resistor. If a
low pass filtering function is required, then an input
coupling capacitor is needed. The values of these
components determine the voltage gain and the bandwidth
frequency. The battery positive supply voltage requires a
good decoupling capacitor versus the expected distortion.
at least 4 layers, a single 4.7 mF filtering ceramic capacitor
on the bottom face will give optimized performance.
NCP2820 is suitable for low cost solution. In a very small
