Part Number: OPA653 Other Parts Discussed in Thread: OPA659EVM Hi Team,
Goo day.
My customer is looking into our OPA659EVM layout. There is a window open in all of the ground and power planes around the IC. In this case, 50 ohms of microstrip lines…
Other Parts Discussed in Thread: OPA653 , TINA-TI The circuit shown in the TINA-TI reference circuit file, SBOM352a (although labeled "SBOS348" in the title block) has two 350 femtofarad capacitors tied from both of the OPA653 inputs to ground. In addition…
Other Parts Discussed in Thread: OPA659 , OPA653 Hi Everyone,
I want to Amplify( non-inverting) / buffer high speed sinusoidal signal of frequency upto 100MHz and Amplitude = 4V i.e. 8Vp-p without loading the other circuit components in shunt.
For…
Actually guys,
Part of a family of JFET parts we developed (table 5) - this one is using the high transconductance input stage along with higher Iq to get the very high slew rate in a unity gain VFA. Nothing to do with the output stage which is topologically…
Hi Alex,
Ok so there are fast transients; when you mentioned decay I was hoping that the bandwidth need was not too high. The OPA653 is another option, fixed gain of 2V/V (6dB) and similar slew rate and bandwidth with 30% lower noise. I think that's…
Other Parts Discussed in Thread: OPA653 , OPA659 , TINA-TI I notice that in the OPA659 TINA-TI reference circuit there are those mysterious 350 femtofarad capacitors from inputs to ground just like in the OPA653 reference circuit.
Is this the input…
Part Number: OPA692 Other Parts Discussed in Thread: OPA656 , TINA-TI
Thanks for your suggestion in the previous answer. The rise time of my signal is 30 ns and OPA656 looks very good for my application. I also tried to use it for a level shift. I defined…
