Question asked by HOD on Apr 27, 2018



I have a question ADN8834 TMPGD.


TMPGD function:
When the AMP output voltage Vout 1 reaches the IN 2 P temperature set value (TMPSET) voltage, TMPGD becomes "H"

Thing you want to do:
Set IN2P to 1.5 V and set the resistance constant of the circuit so that the output of TMPGD becomes "H"
PD temperature 35 degrees resistance 6282 Ω ± 10% I want to move TMPGD to "H" in this resistance value range, but it does not work well.
I changed R4 to variable resistance and tried to vary it from 1kΩ to 50kΩ
A good resistance value was not found.




Best Regards
