Why is my analog module not driving my actuator to 100%


30 September 2021

The most common mistake is that you are attempting to drive a load (Actuator) that exceeds the module load impedance specification.
For example: The load impedance specification for a BMXAMO0802 = 350 ohm Load impedance.
  • If the actuator has a impedance of say 400 ohm, then the analog module will never be able to drive the actuator to 100%
  • It will still drive the actuator, just never to 100%
