Part Number: OPA2192 Other Parts Discussed in Thread: OPA2140 , LMC6482 , OPA2992 Tool/software: I'm looking to identify op amps for a design headed to space. Looking for a recommendation or a way to search for qualified parts. Other similar amplifiers…
Dear Sima,
Thanks for the suggestions.
- Input of THS is from OPA2992. Do I need to consider the output impedance of OPA2992, which varies with the frequency, to calculate Rf and Rg values.
- Application notes suggest to choose Rf < 1k, what would…
Part Number: LM5022 Other Parts Discussed in Thread: OPA2992 , OPA455 Tool/software: Good day,
I have built a 20VDC - 40VDC converter following the design guidelines from the datasheet. It is producing 40V as expected with no load.
However, its voltage…
Li,
This could work if there is enough ICC at min output voltage to keep PMOS on.
Gate could be 2.5V instead for a lower Vout min. This would probably be better.
During ICC below 2.5V, both 2.5V and 5V will be close to ICC so PMOS off either way.

Part Number: LM6144 Other Parts Discussed in Thread: LM6142 , OPA2994 , OPA2992 Tool/software: Hello,
I am using LM6142 & LM6144 in my design, and they are powered from 12V & -5.78V.
I am contacting you in regards to the the bias current value…
Hey Yishan,
I recommend the customer change from the OPA2991 to the OPA2992. Here are test results:
2.21V, 900kHz (blue is input, yellow is output):
OPA2990
OPA2991
OPA2992
The slight mismatch at the bottom of the signal (0 Vand V-) is where the output…
Hi Sumeet,
Marek is OOO. I can assist you.
If you changed the op amp from OPA2328 to OPA2992, here is the simulation, see the attached file.
Sumeet OPA992 application 06052024.TSC
Please let me know if you have other questions.
Best,
Raymond
Hey Michael,
Good to hear the TLV9361 is a good fit for the application. Thank you for sharing
The TLV is a similar design to the OPA version with a lower cost and reduced performance, here is a comparison table.
As you can see in this scenario, the…
There is no pin-compatible device with the same electrical characteristics.
The LM7332, LM8272, and maybe OPA2992 have somewhat similar characteristics; I do not know if they would work in your customer's unknown circuit. See here for a compariso…
Part Number: RC4558 Other Parts Discussed in Thread: RC4580-Q1 , OPA2992-Q1 , TLV9362-Q1 , RC4580 Hi team,
Could you please kindly help recommend an automotive audio buffer device like RC4558?
Customer is using DSP output RCA signal about 2V，they need to…
