Part Number: OPA140 Tool/software: Hi Alec,
Thank you very much for your detailed response, and apologies for the delay in getting back to you. The project is currently on hold and may be moving in a different direction, so we won’t be needing an op…
Part Number: OPA140 Tool/software: Hello,
We are working on a very sensitive amplifier to interface with a high impedance sensor.
I discovered that the datasheet and the simulation model doesn't include the current 1/f noise.
We need to make sure…
Part Number: OPA140 Tool/software:
I am about to start working on a project that requires analog electronic components, particularly operational amplifiers (OpAmps) and passive components, for use in a cryogenic environment (temperatures of 3-4 Kelvin…
Part Number: OPA140 Tool/software: Hi, datasheet bring nominal value 7pF.
How is controlled this 7pF? It's a trimmed capacitance to match this number always? What's the tolerance of this parameter? Changes against temperature?
This value is highly…
Part Number: OPA140 Tool/software: Is there a plot for the OPA140 of input bias current vs temperature? The datasheet only shows +/-0.5pA (+/-10pA max) at 25C and +/-3000pA max over the whole temperature range, but I'm assuming it's not a linear ramp…
Part Number: OPA140 Tool/software: Hey Precision Amps Team,
I have a customer evaluating the OPA140 for a design and we are hoping you can help to provide feedback on expected input bias current performance over temp. There is a plot of I_B over common…
Part Number: OPA140 Other Parts Discussed in Thread: OPA4140 Tool/software:
kindly help us to find the IC Manufacturer Part No from the available top marking in below image
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?
