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?
Thank…
Part Number: OPA858DSGEVM Other Parts Discussed in Thread: OPA858 Hi there,
I was hoping to get help with the OPA858 amplifier.
Initially it was included in the PCB layout to be used as a Transimpedance amplifier, but now there is a plan to use it as…
Part Number: OPA858DSGEVM Other Parts Discussed in Thread: OPA858 , Hi there,
I acknowledge that this may seem like an obvious question but I was wondering if I could get assistance with testing out the OPA858 amplifier as a Transimpedance amplifier. I…
Part Number: OPA858 Hi,
The OPA858 Spice model states that both a common mode and a differential input capacitances are 0.05 pF.
Its data sheet shows 0.62pF and 0.2 pF, correspondently.
Why is such a difference? Is this from the package?
Thank you
Part Number: OPA858 Other Parts Discussed in Thread: OPA847 , OPA818 , OPA659 , OPA657 I love the OPA858 with it's high bandwidth, slew rate, low noise voltage density and low input capacitance.
Does TI have an op-amp with similar specs to the ones I…
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…
Part Number: OPA858 Other Parts Discussed in Thread: OPA818 Hello,
I want to setup an AC-coupled noninverting amplifier based on the OPA858 operating from a single 5V supply with an overall passband gain of 76V/V (37,6dB) and a minimum bandwidth of fCT…
Hi Sima
Yes, it is. I'm talking about this diagram.
In the explanation of this diagram, it says this about Riso
” Add an isolation resistor RISO as close as possible to the inverting input of the amplifier. Select the value of RISO to be between…
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…
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…
