  • TMUX7462F: Protecting 3-Wire RTD sensor to 48V overvoltage on inputs

    Resolved
    Part Number: TMUX7462F We need to protect a 3-wire RTD measurement circuit to 48V short circuit on any input. Would one TMUX7462F powered at 10V accomplish this task? We need to clamp the inputs to maximum 3.3V, so can we assume we need to connect Vfp…
