ANMG04 (4-CH Auto Sensitivity Calibration Capacitive Touch Sensor)
11.2 Example – Power Line Split Strategy PCB Layout
A. Not split power Line (Bad power line design)
The noise that is generated by AC load or relay can be loaded at 5V power line.
A big inductance might be appeared in case of the connection line between main board and display
board is too long, moreover the voltage ripple could be generated by LED (LCD) display driver at
VDD (5V).
B. Split power Line (One 5V regulator used) – Recommended
C. Split power Line (Separated 5V regulator used) – Strongly recommended
