This board unfortunately does not provide detailed specs or a schema.
The assumption is that the ADC is powered by 3.3V and hence input voltages above 3.3V will damage the chip or cause malfunction.
Measure the supply voltage of this chip, pin7 to pin14. Voltage around 3.3V means: limit input voltages to 3.3V.
