My customer has the requirement for preventing the excitation outputs misconnection.
Can the excitation output pin survive when they short to AVDDor GND?
Do you have idea the circuit of the customer? Was the Excitation connected to a buffer? The Abs Max rating should be referred to, any levels beyond the abs max rating may cause damage to the part.
The circuit below is a half of the buffer, The Net name "EXC_1210" is connected to one of AD2S1210 Excitation output pin, The Net name "VCC_Aux" is DC power = 14V,
and the Net name "RDC_OUT_N" is the output of my board, which need to be protected from short circuit.
The "RDC_OUT_N" output have to pass ISO 16750-2-4.10“Short circuit protection”experiment , Which endure 0V and 16V within 60s respectively.
Do you have any suggestion about how to do?
