Table 31: Operational Range
The ∆Σ ADCs can operate in differential or single ended mode. In differential mode the differential input
voltage range must be in between -2.5V and +2.5V. However, it is recommended to use the input voltage
range from -1.25V to 1.25V, due to non-linearity of ∆Σ ADCs. In Single ended mode the operational input
range of the positive input channel should be between 0V and 2.5V. Recommended maximum input
voltage is 1.25V. ADCs have
