Part Number: OPA140 Other Parts Discussed in Thread: OPA320 Dears:
Customer use OPA140 to do voltage track circuit. They found abnormal noise in output voltage.
Green waveform is input sine voltage. Blue waveform is output sine voltage.
1- the noise overlap…
Part Number: OPA140 Looking at the Revision History in the datasheet, there is no mention of any changes from Rev. B to Rev. C. What is the difference between Rev.B and Rev.C?
Part Number: OPA140 Other Parts Discussed in Thread: OPA192 , OPA828 , OPA1677 , OPA4192 I would like to verify that the common-mode input voltage range is correct on the datasheet, (V-)-0.1 min, (V+)-3.5 max. For a ±15 power system that limit the common…
Part Number: OPA140 Other Parts Discussed in Thread: DIYAMP-EVM Hello, I would like to ask, when testing the OPA140EVM board, the power supply is a tracking circuit, and Vcc is a plus or minus 5V power supply. When Vin=4.5V, it dose not meet the range…
Part Number: OPA140 Other Parts Discussed in Thread: OPA1641 , OPA145 , OPA141 , Hello,
In a previous board, I was using OPA140AIDBVR. This component is out of stock.
Would you have an alternative with very close caracteristics, which can be bought ?
If in…
Part Number: OPA140 Hi team,
One of our customers saw the following document in the OPA140 datasheet
FEEDBACK PLOTS DEFINE OP AMP AC PERFORMANCE : https://www.ti.com.cn/cn/lit/an/sboa015/sboa015.pdf
During the study of the SBOA015 document, this customer…
Part Number: OPA140 Hi Team,
Customer is asking if we can provide Gain & Phase vs Frequency raw data?
OR how could we get this 'raw data' from simulation (like TINA?)
Thanks!
Andrew
Part Number: OPA140 Other Parts Discussed in Thread: OPA192 Hi Team,
Customer is checking with us if this is normal simulation gain/phase data is not 100% matching to datasheet, or we suppose to do a small fix for OPA140 model in near future?
Thanks! …
Part Number: OPA140 Other Parts Discussed in Thread: OPA1642 Hello,
I'm doing to use OPA140 in my new design but can't find anywhere whether the op amp is fabricated with a DI process or not.
Any information is highly appreciated.
Thanks
