I would like to know for the part REF43, pin 1 and pin 4 are they suppose to be shorted?
Found that pin1 and pin4 are shorted when tested using multi-meter.
Thanks& Best Regards,
Pin 1 is use for production testing. It is recommended to not connect anything on that pin.
Connecting something on a Production Test pin may trip the inside of the Reference to be off specs…
