Re: DDS-3 version 8 map sensor problems
Pin7 of the DDS3 has a weak pull-up resistor inducing approximately 0.1mA. Can you check the maximium current output of your MAP sensor with a DMV.
Who is the manufacturer of this MAP sensor? A typical GM MAP sensor has an output current of 25mA. If you use this sensor, the output voltage should not be affected by the DDS.
