Comparator Click Board
IC/module: LM2903 IC
The LM2903 IC consists of two independent precision voltage comparators on the click board that operate over an extensive range of voltages. The comparators can operate from a single power supply as well as dual supplies.
How Does it Work?
When paired with analog sensors, Comparator click allows user to hook up an analog signal. The voltage from this analog signal is used as an input and compared with the physical value set as a reference by using the potentiometer. The device will then digitally check if your input voltage is higher or lower than the referenced value. If the input value exceeds, an interrupt signal is triggered.
Power: Single-Supply or Dual Supplies
Comparator click is designed to be used with single or dual power supply. For single power supply—the offset voltage can be as low as 2.0 mV, with a range from 2.0 VDC to 36 VDC. For dual power supplies—the range is from ±1.0 VDC to ±18 VDC. The resulting output is compatible with TTL, DTL, ECL, MOS and CMOS logic systems.
