Hi all,


Need your advice, if AD8436 can be use to measure DC current for 3.3V, 5V and 12V.


Attached is the block diagram.


1) To measure the current going into DUT(Device Under Test)

2) A shunt resistor is place between IBUFIN- and IBUFIN+

3) The output from IBUFOUT is connected directly into RMS (without cap) since it's a DC voltage.

4) OUT to connect to customer MCU to measure the current.
