Other Parts Discussed in Thread: ISO7842, ADS131M06, ISOW7842
I am making an industrial data acquisition module using ADS131M06. I wanted to isolate the ADC supply from the main supply along with the communication lines to the microcontroller. I saw the reference design of achieving the same with ISOW7841. But in my case I wanted two additional lines also to be isolated which are DRDY and RESET. Here I have two options one is adding another ISOW7842 and cascading the isolated power supply together or use ISO7842 and drive the isolated channel powersupply using ISOW7841. In the second case I dont know that the ISOW7841 has enough power to run the second ISO7842. Attaching the schematics of both proposed solutions. Please let me know is it feasible?
