Part Number: ADS8867 Other Parts Discussed in Thread: OPA313 , INA333 , INA133 Hello,
I have handed over design that uses ADS8867 for Wheaton Bridge reading. O/P of that bridge is 80mV and gain before feed to ADS8867 is 11x.
AINN is 1.25V, AINP is output…
Thanks Tim, that's good to know. Both the OPA313 and OPA316 have been updated recently and are running our latest model architecture, so I'm glad to hear that the results agree in both tools.
I'm going to send you a friend request, let's take…
Part Number: OPA211 Other Parts Discussed in Thread: TINA-TI , , OPA313
Tool/software: TINA-TI or Spice Models
Dear Miss, Dear Mister,
I'm currently simulating a current source which use the OPA211.
Unfortunately, the behavior of the circuit is quite…
Vidula,
Since you use a lower precision, 0.2% initial accuracy reference voltage, REF3030, there is no point on using high precision, more costly op amp for driving REF pin of INA333. Therefore, the cost effective solution would involve using OPA314 or…

Can you please let me know the best device to compete against the NCV2001? The device needs to be footprint…
Hello Vijith,
You should be able to store the TINA file I sent you, OPA313 Cap Divider_01.TSC, and then open it from TIINA-TI. Once the OPA313 model shows in the circuit you can copy and paste it into your own schematic.
I checked the model library updates…
Hi Yu-Hung,
When I ran the simulation with the THS4531 I looked at the voltages at the input pins...even though you're applying a +/-12V signal, the voltage at the THS4531 input pin is attenuated by the feedback resistor network, as shown below:
…
Hello John,
Find attached my test benches.
Here are my inputs about the 5 different benches I sent:
OPA313: unsimulable, it's look like there is an error in the model. The simulator give the following message: " ERROR(ORPSIM-15143): Voltage source…
Colin,
Your description of Op Amp behavior is in line with my observations during the "stuck" condition and how it is impacted by more load current or a disturbance on the IN+ input.
By lowering the FET Vds we have been able to place a limit…
