I am trying to use a single AD598 with 8 no's of LVDTs.
I am planning to switch the primary excitation and the secondary of the LVDTs to the AD598 via multiplexers.
Please find a concept schematic attached here. (Please ignore P/N of the muxes)
(EDIT: I am checking ADG1409)
Can someone guide me in the correct direction by pointing to correct devices (multiplexers) to use?
Pretec LVDT probe 2924 (+/- 1mm)
Freq : 13KHz ( I may use 3KHz)
Resistance : 2K (so excitation current is 1.5mA)
Apologies for the delayed response here,
I think you are on the correct track here with the ADG1409. the first thing to think about when selecting a switch is the Supply voltage and the voltage you wish to pass.
If you are using a +/-15 V supply (same as the AD598) then the ADG1409 would be the correct choice.
