ISO1228DFBEVM: Verify the Source/ sink in evb

Part Number: ISO1228DFBEVM
Other Parts Discussed in Thread: ISO1228

hi Sir

I already can reading the ISO1228 status by MCU with ISO1228 EVB

I apply the 24v to J2 ch1~ch8, i can read the correct status that is sink mode

may i know how to verify the source mode in same evb?

thanks

  • Hello Alex,

    The current EVM only performs sink-type operation. In order to test source mode with the current EVM, you would need to modify the EVM's components to match the below topology. The components on AVCC and AVSS and the LED would need to be rearranged as shown below. 

    Best,
