Part Number: OPA858 Hello,
I have designed a AC-coupled non-inverting amplifier circuit as shown in the picture below. Thanks to the help of this forum the amplfier itself is stable and so far the results are quite promising. However when i do a spectrum…
Other Parts Discussed in Thread: OPA858 , THS4541 Hi All,
I exported the OPA858 model into LTSpice but when I run a simulation I have the following problem:
ERROR: Node U1:I0:I21:1:102 is floating and connected to current source G:U1:I0:I21:1:RA ERROR: Node…
Hello Libin,
Sorry for the very long delay on this. I have an issue on my end with PSpice for TI that is going through some fixing, so I had to switch over to Tina-TI. The below images/simulations are from Tina-TI, but you can continue using Pspice for…

Hi, i'm trying to find a suitable substracting OpAmp that will allow me to substract two DC signals that represent the output power of a PA, these signals…
Part Number: OPA858 Hi Team, Our customer would like to ask if it is possible to use PIN diodes in lieu for the APD diodes in designing with OPA858? Asking for this possibility as PIN diodes are much cost-efficient solution and doesn't require high voltages…
Hi Raymond,
well, the major issue here is that the photodiode is distanced too far away from the OPA858. Move the photodiode as much to the OPA858 as you can
Also, I would ground the metal housing of photodiode.

Part Number: OPA858 Hi Team, the customer wants to confirm if these devices are supported on LTSpice. They tried to use the PSpice model however it is encountering error.
Hoping for your kind response.
Thanks.

Part Number: OPA858 Other Parts Discussed in Thread: TINA-TI Hello,
I am using TINA-TI for simulating my circuit and have a question regarding the OPA858 model.
Does the model include the inut capacitance or do I have to include it in my circuit using…
