Other Parts Discussed in Thread: TMUX1308
Hi Team,
I would like to get your help in confirming the customer design below for TMUX1309.
The customer has 8 voltages to measure using TMUX1309. They are around 30V.
All 30 V sources are with respect to Gnd which has the same potential with Vssa
In order not to repeat the same resistive voltage divider circuit. They have an idea to place the lower resistor to the output of TMUX and using only high side resistors at the inputs
Is this solution reliable for continuous operation?
The customer needs 10 samples per second
The ADC is one of TMS32F280049 ADC channels
Please let me know if you have any questions to confirm the customer design.
Thanks,
Jonathan
