ADG1606 ESD protection

Question asked by PDES on Apr 2, 2012

I use an ADG1606 and others analog muxes in an analog front-end stage.

The ADG1606 serves to multiplex the excitation current required to acquire 16 RTD sensors.

I cannot use resistors in series with the inputs of the multiplexer.

It's preferrable to use  external TVS array diodes, in order to protect the mux or the internal protection should be enough?


thanks in advance
