Thanks for the suggestion and feedback. It was really helpful! We will
order this product once we finalize on the other stuffs on our PCB.
Thanks & Regards,

I am using ADA4817-2 part in my on going project. I have query about driving capacity of this OP-AMP. I am using this OP-AMP in unity gain configuration mode (Voltage Follower). I want to know how much load capacitance it can drive.The series…
Basically you may build a simple oscillator with a high frequency & high slew-rate Op-AMP like a ADA4817-1
I have certain amplifier design comprised of 2 stages, the first one is TIA configuration based on National's LMH6624 and 60.4k feedback (gain) resistor.
Recently the amplifier TIA stage has been updated replacing the LMH6624 by ADA4817, this…
I am thinking that at your current setup, the cables are properly terminated at 50 ohms. And the AD8099 and ADA4817 are set at a gain of 2 V/V to compensate for the termination. Also, note that at gain of 2 V/V ADA4817 only has a large signal…
Sorry for this late response.
The Application Note (AN232) you sighted refers to JFET-input amplifiers that operate on high voltages and have relatively high input capacitance. The ADA4817 has a maximum supply voltage of 10 V that is far…
Hello, I asked the original question. We built the system, and found the following:
1. When the PD is activated the ADA4817 output goes to -V with what appears to be an approx. 600uA current sink. As the output voltage is varied by the other amp in the…
I downloaded the spice model .cir of ADA4817 from the web. Then I Created a symbol with the ada4817.cir .
But , after I put the symbol to my schematic to run sim, ( I gave a 4Vpp sine wave to the input )
There was nothing on the output.…
Do you mean Ada4817-1? Yes, it is possible. Look at http://welecw2000a.sourceforge.net/docs/Hardware/Aktiver_Tastkopf_mit_OPA659.pdf
ada4817 can replace opa659 there.
