PCAN-MicroMod Analog 2 has four analog outputs, each rated 0-10V, based on 12-bit DAC, so it's able to discretize 0-10V to 4096 values. Our specific project needs a voltage range 1.2-3.7V on one output/input, and the resulting number of steps Analog 2 can produce is not enough to achieve wanted precision. Is it possible (recommendable) to scale the output with a resistor that's dimensioned exactly the same as the Analog 2's output, so it would divide the voltage by a factor of 2, meaning we'd have 4096 steps between 0-5V?
the 4 ch. DAC used for anaog output has a range of 0...4.096V. The output amplifier has a gain of 2.44 to produce an output voltage of 0..10V.
It is possible to change the gain to 1 to get an output of 0...4.096V (replace a feedback resistor by 0R).
If this is a option for your case please contact us again for the details.

You will get a description how to modify the baseboard PCAN-MicroMod Analog2 to change the analog output gain to 1 to reduce the output votage range.
