Other Parts Discussed in Thread: LMP91000,
Hello
I am planning to use ADS8166 with 4 LMP91000 chips. I wish to use the Internal 4.096V reference voltage of the ADS8166 for the LMP91000 to read output from gas sensors like SPEC sensors. I have the following questions.
1. What will be the output range on VOUT of LMP91000 with internal zero at 50% and bias 0%?
2. How do I match the output from LMP91000 to FSR of ADS8166 (0V to 4.096V)?
3. Do I need to add any gain buffer on the REFIO to use it with the 4 LMP91000 chips? The track length between the ADS8166 and the LMP91000 will be around 2 inches.
4. Do I need to add any buffer between VOUT of LMP91000 and AINx of ADS8166?
Regards
Vijay
