Isolated multiplexer for temperature measurement

Obinna Ezeilo
Intellectual 2385 points

Hi Team, 

My customer is in search of a multi-channel (at least 4 ch) precision multiplexer, isolated from one side to the other, and non-isolated within the input analog channels with a truth-table to decide which analog input to pass through the isolated output.

Can you recommend any specific  multiplexer with at least 4 channels for temperature measurement with the above requirements in mind?

Thanks. 

Obinna.

    Hi Obinna,

    Can you provide details on your input signal voltage, supply voltage for your application.

    Are you looking for isolation when there is no supply to the switch (Vcc=0V)?

    Take a look at the TMUX1511 which is  1:1 SPST switch configuration with 4 independently controlled channels and provides isolation when the supply voltage is removed (VDD = 0 V).

    Regards
