Other Parts Discussed in Thread: TINA-TI
Hello,
I can't get the numbers according to the SNOA997 document that shows an example about how to design an inverter comparator with hysteresis.
I'm trying to get the numbers of the example and I'm getting negative values for the feedback resistor R4, when should be 808kOhm.
It's just to solve for the the quadratic equation for R4 but I can't get the expected value.
See the attached template that follows the example described, I think it is ok and do not know where the error is comming from.
Anyway, I would like to design according to the following parameters:
Vlow = 1,06V, Vhigh = 2,24V, Vcc = Vref = Vpu = 10V.
Vo = "High" when Vin>Vhigh
Vo = "Low" when Vin<Vlow
I would like to use TLV3401 but some others compatible can fit as well.
So, I would need to fix this problem with calculations in the template.
Could you please give feedback on this and help me with this issue?
Regards,
