DRV3256-Q1: What to do when ADC reference voltage is outside of DRV AREF accepted range

Hey BLDC team,

I have a customer evaluating the DRV3256+AM2634 for a new project and we are wondering what the recommended solution would be for using the MCU's ADC reference voltage for the gate driver's AREF pin. The AM2634 has an ADC reference voltage of 1.8V and the DRV3256 AREF accepted range is 3.3-5V.

Do you have any guidance on how to address this? The DRV3256 datasheet specifically recommends that the ADC reference voltage be used for AREF.

Best regards,
