ADG1606 ESD protection

Thread Summary

The user inquires about protecting the ADG1606 analog multiplexer used for RTD sensor excitation currents. The final answer indicates that the ADG1606 has a 1kV HBM ESD rating, and external TVS diodes should be used if higher protection is needed. The accompanying answers clarify that ESD ratings are not always included in older datasheets.

Hi,

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
