Voltage Level Detection

Voltage Level Detection

Safety Features Application

Some applications require multiple voltage levels to be evaluated, rather than a few distinct levels. This application shows how to use of ACMPs, DCMPs, and an ADC to monitor the voltage amplitude.



  • Any GreenPAK with ACMPs, DCMPs, and an ADC
  • Up to eight LEDs and resistors

Design Steps

  1. Power on the ADC, DCMPs, and ACMPs.
  2. Configure the DCMPs using Technique: Using DCMP PWM block in PWM mode.
  3. Set the IN- of each ACMP and DCMP with the desired voltage threshold levels.
  4. Add LUT and DFF logic to select and write data of the amplitude of the analog voltage from DCMP1.
