Specifications
Absolute Maximum Ratings
Stresses above these maximum ratings will cause permanent damage to the device.
Exposure to absolute maximum conditions for extended periods may degrade device
reliability. Proper function of the BrioSens at or beyond the specified
operating conditions is not guaranteed.

There are four analog inputs. Each input provides 16 discrete levels of gain
that is software selectable. Gain and current loop (4-20 mA) mode are
independently configurable for each input. For more information, refer
to the ADC peripheral section.
