Is there any required external circuitry for the ADC?

I am using a current sense amplifier (INA190) to measure current. The output of the current sense amplifier will go to the input of the ADC on the STM32. The output range will (ideally) be between (0-VREF). From working with an external 16 bit ADC, I...
