    Thanks Ian, Understood. Am using the A2 version for 5V high side sensing. Also found the 500K Ref impedance buried in the text description. Would be useful if that was listed in the specifications. I settled on a TLV431A low power shunt reg with minimized…

    Hi Vincent, 1. The voltage reference on the secondary side (D27) should be TLV431A (the low voltage variant)*** 2. How come you change the R9 resistor from 1k to 100ohm? Regards, Tom A.
