Tool/software:
Hi Team,
I am using two INA240A1-Q1 IC used for measuring same current based on project requirement. (like below). We used different (Supplier) LDOs for providing supply to each INA240A1-Q1 IC.
Now i am planning to calculate error budget for CSA amplifier.
My LDOs tolerances like LDO_1 ==> 3.234V to 3.366V & LDO_2 ==> 3.201V to 3.399V. My operating temperature is -40C to 85C.
I need clarification for below point:
Q). Shall i consider both CSA amplifier tolerances single side only ( like +Ve tol. or -Ve tol.) or Do i need to consider worst case (one is min & one is max)??
If i consider worst case then my error budget value is high. (In calculation included Gain error, offset error, Reference divider tolerances & supply tolerances).
Thanks & regards,
Giridhar.
