I'm curious as to whether I could use two iDAC to create a constant current biphasic pulse to stimulate biological tissue. I don't completely understand the iDAC compliance voltage and how it would relate to my project. I would like to produce a 100 microAmp pulse with a total duration of 1 ms, and the load will be 0.5-1.0 MegaOhms.
Cound someone comment on the iDAC compliance voltage, and if my load and current requirements would be possible using the iDAC.
100uA into 1Mohm means 100V across the load. Don't think you can use the pSoC IDAC directly. you need to have external circuitry to do this.
