I use ADUCM360 ADC to detect a light sensor input. Because the input voltage is very small, so I want to know what the minimal voltage for ADC channel.
In theory the smallest input that can be measured by an ADC is equivalent to 1 LSB, but in practice it depends on the noise resolution of the ADC.
Pages 9 and 10 of the datasheet shows the noise figure depending on filter configurations.
Page 32 of the user guide shows how the ADC result is displayed in the ADC data register.
