The forum seems picky on which type of files can be attached. I renamed my JFEx140.asy to JFEx140.asy.txt to allow attachment. I use the ASY file as the symbol and then the jfex140.lib as the model with the LTspice statement ".include jfex140.lib".…
Part Number: OPA892 Other Parts Discussed in Thread: OPA847 Tool/software: I am using the OAP 89s to act as a high gain transimpedance amplifier (50k ohm transimpedance gain with 0.3pf feedback cap) but am having some problems in biasing amplifier.

Part Number: OPA891 Other Parts Discussed in Thread: OPA892 , , OPA2892 Hello Experts,
This board will be used for designing a probe for measuring switching currents of a high-speed SOC.
The input voltage range is expected as 250uV to 7.5mV.
OPA891 and…
Part Number: OPA862 Other Parts Discussed in Thread: OPA892 Tool/software: The signal input to the OPA862 is generated by an oscillator. The circuit generated by the ICM7555 had differential outputs. On the other hand, the circuit generated by the SIT2001BC…
Hi Igancio,
Is there a tutorial on how to import an op amp package (provided by TI) into TINA? IT has been very difficult to do that with opa892. I put in a ticket to get in touch with you about this, but never heard back. Thanks!
Sumeet,
Assuming a bandpass filtering shown below, using OPA892 with its broadband noise below 1nV/rt-Hz would result is the input referred noise of around 152nVrms (1.52mV/10,000) and thus could be able to measure a piezo signal in hundreds of nV - see…
Hi Andri ,
Yes increasing the IDS current will increase the gain. I have simulated and added the instructions on how to run the gm simulation below. With the new IDS current the gm is now approximately 10.28mS.
Note that your Vds voltage is in a good…
Hello Anil,
The THS4021CDGNG4 is obsolete. The THS4021CDGN is available as an 'active' product. We also have the drop-in replacement p2p compatible OPA892 , which is recommended for new designs.
Please let me know if you have follow-up questions…
