Part Number: INA333 Other Parts Discussed in Thread: INA826 Tool/software: Hello TI Team,
I intend to interface the 3 wire RTD with the INA333. Could you please suggest the design for it ?
I appreciate your feedback. Please revert asap.

Part Number: INA333 Tool/software: Hi, I designed a RTD circuit with the help of INA333, Issuse is the output not varying linearly w.r.t Vdiff. please find the below images.
Additionally, when the RTD is disconnected, the difference between IN+ - IN…
Part Number: INA333 Tool/software: when the RTD is disconnected, the difference between IN+ - IN- is approximately 9.5V, it cause to damage IA's, Could you explain the cause of this and suggest how to protect the circuit under these conditions?
Hi Jigar,
Jigar Jain said: But i dont understand why this is not working in simulation model ?
When you say simulation model, you mean TINA-TI / PSpice simulation?
These models are not designed for replicating the common mode vs output voltage plot.…
Part Number: INA333 Other Parts Discussed in Thread: TINA-TI Tool/software: Hi, I have a bunch of existing circuits that are currently working well in LTSpice and I need to integrate the INA333, but the model just causes LTSpice to bog down and never…
Part Number: INA333 Tool/software: Dear sir,
We have configured the INA333 for a single-supply, single-ended input configuration in our custom project. However, we couldn't find any reference to a single-ended input application in the datasheet. Could…
Part Number: INA333 Tool/software: Hi team,
We are using INA33 instrumentation amplifier for our new project. We are using INA333 in single supply mode operation. We have connected V+ pin to 3.6V and V- pin to GND. SInce it is a single supply mode,…
Hey Ben,
No worries! Yes, adding a sufficiently smaller third resistor will cause the smaller resistor to dominate the error analysis. If you are looking at how to add in an integrator, the easiest method would be to buffer the mid-voltage point. This…
Okay, so as expected, poorly-designed off-the-shelf filtering - thanks both of you. The TINA simulation indicates it's better without and removed them on one board and not really seeing any improvements so still trying to work out the dependent variable…
