Part Number: OPA141 Hi Experts,
Good day.
A client is trying to use OPA141 to make a product. For that, they would like to evaluate some of the performance of this op amp more accurately.
Hope you can tell us how to test out the curve graph for…
Abbas,
Without getting into the merits of your concern about the input current noise contribution (thermal noise will dominate the total noise for high input source impedance), I would like to point out that the input current noise is a function of…
Oh yes, thanks Kai. Didn't go through the datasheet before answering. Also, is OPA141 the best option for transimpedance amplifier for signals less than 20Hz?

Other Parts Discussed in Thread: OPA141 Hi i have the opa141 connected in a non inverting amplifier.
weirdly, if i put a high resistance value >1M at the non inverting input to ground (because i have a high pass filter at the input), the op amp becomes…
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…
Hi Kai,
Thanks for your response. Actually, the starting amplitude is not always 200mV but it is in this order. It would vary from 50mV up to 250mV in different cases. Also, I know that this process can be done using series of OPA141 op-amps but I…
Hi Thomas!
Thank you very much for this explanation. Now we are thinking about two devices: more expensive but ultra low noise version with OPA141 and low-cost with some different amplifier. Because our volume is not very high, may be it is acceptable…

Part Number: ADS8691 Other Parts Discussed in Thread: OPA141 , Dear All,
My last problem was solved with your help. Thanks again.
When the ADC input test was performed based on the completed code, it was found that the converted value was abnormal…
