Part Number: ADS1261 Other Parts Discussed in Thread: TMUX6104
I am designing an RTD measurement device based on ADS1261. The excitation current requirement range from 100nA to 1mA, I understand that I need an external current source to support this…
Thank you for your response!
Can you explain, please, how TMUX6104 can deal with 20+ Volts, if datasheet says: VDD to GND - maximum 18 V? TMUX6104 is 36V only with dual supplies.
Part Number: MUX509 Other Parts Discussed in Thread: TMUX6104 e2e,
Could you recommend proper device?
Replacing DG409 with independent control for each ch
We have alternative device to replace DG409 but control pin controls 2 chs in the same time…

Do you remember me? I sent my SCH to you ,Please check the schematic diagram for me,TKS! SCH20200220.pdf
user5994204,
I would use the TMUX6104 device which will support +/- 8V signals @ 20kHz and you can set the A0 and A1 pins to select connect the signal to one of the 4 outputs. Adding a weak pulldown on the out will ensure that the node is not floating…
Kenneth,
I couldn't find a device that meets all of your requirements.
It looks like you will need to use a level shifter on the control logic pins to support the 1.8V logic control if you use a device like the TMUX6104 or CD4052B.
We will…

TMUX6112 P2P With ADI/ADG441
TMUX6112 Rdson is larger than ADG441,IB less than ADG441
In Mux, Could you let me know which feature is importane for customer? Rdson or IB?
Mateusz,
The +/-18V supply requirement will quickly filter the number of options in the current TI switch portfolio. What do you think about the new TMUX6104?
Thank you,
Adam
