Ok so I’ve got the One Channel 0-10V DAC working. But sending 4095 to the DAC for maximum ouput produces around 8.9V. My setup is as follows:
- Arduino Nano (tried with UNO too)
- Desktop Power Supply outputting exactly 5.00V with “unlimited” power available.
- NANO is mounted using the NCD Interfact module
- Interface is connected using the provided cable to the DAC
- Signal is being read using a multimeter at the output ports.
Touching the screws vs the actualy terminals is a trivial difference in voltage seen.
As one may expect, powering the NANO via a USB port on the computer produces an output around 8V.
Should i be cranking this up to 5.5V or higher to ensure I’m getting the proper range?? I could expect some loss, but when I’m trying to access the full signal range of the device i’m trying to control… I can’t miss out on a full 10% of the usable range of the device.
