NOTE:

Ensure that the comparator input terminals are connected to signal, power, or ground level. Otherwise, floating levels may cause unexpected interrupts and current consumption may be increased.

slope a/d conversion

The Comparator_A is well suited for use in single or multiple-slope conversions. The internal-reference levels may be used to set a reference during timing measurement of charge or discharge operations. They can also be used externally to bias analog circuitry.

Voltage, current, and resistive or capacitive sensor measurements are basic functions. The sensors sense physical conditions like temperature, pressure, acceleration, etc.
