Hi Folks ? I have a question about power down input protection for the ADC circuit for the LPC213x processors - does the LPC213x have a JFET or similar protection for the input ports of the ADC circuit to isolate the circuit from any external voltage when the power is down? I?m working on an existing LPC2138 based product that uses a 3V lithium battery to back up the RTC circuit (Vbat) ...
