Part Number: TMUX1308A
Other Parts Discussed in Thread: TMUX1308, SN74LV4051A

Tool/software:

Hello,

My customer wants to use the TMUX1308A to select one of several voltages and send it to an ADC input as shown below to monitor each voltage level.

Is TMUX1308A the best product for this application? Please recommend a more suitable product for this application, including information on lead times, low-cost solutions, etc.

Thank you.

    The mux's supply voltage must be at least as high as the highest measured voltage.

    For measuring DC voltages, the electrical characteristics of the mux are not really important.

    TMUX1308 or SN74LV4051A would be cheaper.
