Part Number: OPA858DSGEVM Hi,
I purchased an OPA858DSGVEM board recently.
I tried to connect Split sources, GND, and keep J4 on.
I only used the Negative input (J1) and make the Positive side(J2) floating.
Unfortunately, I cannot get anything…
Part Number: OPA858 Other Parts Discussed in Thread: TLV3801 , TINA-TI Hi TI
We need to thoroughly examine the transient time characteristics of the OPA858 in relation to the power_down enable/disable feature. Specifically, what is the maximum time…
Part Number: OPA858 Other Parts Discussed in Thread: TMUX1112 , OPA859 , OPA857 , OPA3S2859 , TMUX1511 Hello everybody,
at the moment we are busy designing an application to evalute OTDR Pulses. So we choose OPA858 as a fast Opamp in a TIA application…
Part Number: OPA858 Hi Team,
1.The customer use pspice to simulate the open loop gain of OPA858, but it doesn't meet the data in the datasheet, only3.2G.
Here attached is the simulation files and snippet.

Part Number: OPA858 Hi,
We have submitted a PCN to our customer regarding OPA858 wire bonding change (Au→Cu).
Therefore, we have the following inquiries. The customer uses this part as a very high speed TIA and is concerned about the impact of the…
Part Number: OPA858 Hi team,
When we used OPA858 for signal amplification, we found an abnormality. The circuit is as shown in the figure below. When the IN+ input is 0V, the output is 1.7V. The output should be 0V. Could you help with this? Thanks…
Part Number: OPA858 Other Parts Discussed in Thread: OPA656 Hello Michael,
One more question, regarding the Spice model of OPA858.
Does it model the effect of noise current increase with frequency, as described in OPA858 data sheet on the page 18…

Hello,
I'm simulating the following OPA858 and TLV3603 in series as follows:
Simulation time take very long because of pseudotransient Convergence as follows…
Part Number: OPA858 Other Parts Discussed in Thread: THS4541 Hello all,
I am trying to simulate the noise of the following circuit. The circuit has a transimpedance amplifier (TIA - OPA858) and a fully differential amplifier (FDA - THS4541). However…
Part Number: OPA858 Other Parts Discussed in Thread: TINA-TI , , TPS61391 , OPA356 , OPA695 , OPA859 Hello all,
I have designed a transimpedance amplifier to detect a pulse signal received by a photodiode. V_APD is the APD supply, V_COM is the DC voltage…
