Part Number: TMUX1204

Dear Sir/Ms.

I set resistor divider at S1~S4 and want to get difference at D1. Let me simple fing. my test.

R1 add R2 around 100K.

D1 can not get voltage of R2/(R1+R2). Why? Would you please guide me?

Best Regards,

Are the voltages at S1 and D1 the same? Is there any load connected to D1?

Hi Kami,

Thank you for the diagram.

In addition to answering Clemens's questions: Are the voltages at S1 and D1 the same? Is there any load connected to D1?

Could you answer: What is the amount of difference from the expected voltage and measured voltage at D1? Does this occur for all inputs S1-S4?

Thanks,
Kate
