Part Number: OPA858 Tool/software: OPA858 Inverting Mode Output Distortion Asymmetry Issue
Body:
Hello,
I am using the OPA858 in an inverting amplifier configuration with:
Rin = 100kΩ
Rf = 1MΩ
Non-inverting terminal grounded
Input: 1 kHz…

Part Number: OPA858 Tool/software: Hi Team
Customer using OPA858 in their optical module project. When they use near field probe and spectrum analyzer found 20dBm radiation in 2Ghz frequency point.
This circuit is used in PD light power detection, the…
Hello Deepthi,
Are you able to share an updated schematic? And, are you probing output or directly connecting into a 50ohm match impedance to scope?
Thank you, Sima
Hi Deepthi,
To keep this thread focused on the original topic, could you please open a new thread for unrelated/ new questions? That way, it’ll be easier for others to follow along and find relevant discussions.
Thanks!

Part Number: OPA858-Q1 Other Parts Discussed in Thread: OPA858 Tool/software: i am getting this error while simulating opa858 opamp model . can you please help me with this . Do i have to include any library file ?
Part Number: OPA858-Q1 Tool/software:
this is the circuit diagram and without giving Vin also inverting terminal has 0.1V when measured with multimeter.
i am capturing the data of bias current from SMU ,which can capture upto pA .So, won't it work for high values of feedback resistors? I chose this amplifier specifically to achieve a transimpedance gain of 1 GΩ. Do you have any suggestions on how…
Part Number: OPA858 Tool/software: Hi,
I would like to simulate a TIA with very high bandwidth based on the OPA858. I don't have much experience with TIA development or analog circuit design.
Is it possible to use SPICE as a simulation tool for…
