Example 2:
1. The THERMDA and THERMDC tracks Must Not pass through/by PWM
POWER-MOS, Linear Regulator and Clock generator. Keep as far as
possible from POWER MOS.
2. Place an external 3300pF input filter capacitors across THERMDA,
THERMDC and close to the F75334D. Near the pin D- (Pin# 2) Must Be
placed a through hole into the GND Plane before connect to the
external 3300pF capacitor.
