Part Number: OPA192 Hi Shadders,
I think you have short-circuited R3 somewhow when experimenting with the circuit. This would not only explain the damaged OPA192 but also the damaged zener diode.
By the way, I don't understand, why you have mounted…
Hello Shadders,
You mention the input current was limited to 10 uA when applied to the OPA192 inverting input. If the polarity was positive, then the upper ESD diode going from the input to V DD as shown in datasheet Figure 65 could turn on. If forward…
Part Number: OPA192 In aerospace, there is a no floating metal requirement, ex: unused pins are tied to ground through some resistor. What is TI recommendation on NC pins for the OPA192IDR? Leave floating or tie to GND through some resistor?
Part Number: ADS7953 Other Parts Discussed in Thread: OPA365 , OPA325 Hi, Expert
my customer want to use ADS7953, and use example application.
some question need to confirm with you:
figure66 in ADS7953 datasheet , customer want to use 3.3V for…
Part Number: OPA192
Hi,
1. Kindly let me know the Value of maximum current consumption of OPA192 @VCC=3.3V and VSS=-3.3V.
2. I want to generate -3.3V from 5V supply. so how much output current i need to consider?
3. Aslo suggest me any IC having…
Part Number: OPA192 Other Parts Discussed in Thread: TINA-TI Please correct the model.
The new 1.6 version dated June-11-2021 is broken.It is missing parameters.
In line #259 of the model, SW_OL_OPAx192 parameters are missing. As reference, see line…
Hello Jacques,
I believe that your OPA192 comparator circuit is fine as is and the convergence issues you are encountering come down to subtleties of the OPA192 simulation model design and its transient behaviors in the TINA environment. First and foremost…
Part Number: OPA192 Hi,
Let me know the following,
I think that the offset voltage specs over 0℃to85℃ and -40℃to125℃ in the OPA192 D/S include the effect of Input offset voltage drift.
but when I calculate the max offset voltage @ +125℃ from the…
Part Number: OPA192 we are currently using a zener diode in our circuit for input pin protection where leakage current in some parts have become a concern. we would like to remove it altogether if possible given the large resistance already in series…
Part Number: OPA192 Other Parts Discussed in Thread: OPA2192 Dear sir
l use the opa192 as voltage signal amplifier ,the schematic is as follow ; when I short the opa192 output to ground ,the noise figure is picture 1, when the opa192 work on the system…
