Is there a protection loop such as an input current limiting resistor?

Meng jeffrey

The internal input voltage of the TMS5701227CPGEQQ1 is 6.2V, and the supply voltage of the MCU is 3.3V. Is there any protection circuit such as input current limiting resistor inside the MCU and AD?

Hello Jeffrey,

The recommended operating conditions for VCCIO and VCCAD:

The 6.2V is the absolute maximum voltage for VCCAD or AD inputs
