I have simulated AD797 (AD797.cir) noise with LTSpice4, it is as in data sheet around 1.8nV/Hz1/2 @10Hz
Now, i want to simulate ADA4896 (ADA4896.cir) and i find something very different with data sheet...
I think it is because of bad ADA4896…
Our customer have interesting in AD8397 and ADA4896-2 , and have questions need to know further about :
" How do these parts(AD8397 and ADA4896-2) behave when they reach their output current limits?
Do they clip at Io limit, is the…
I must of missed the info on the input range. I think I just assumed it would be to the supplies. So it seems to be doing what it should. Thanks
Thank you so mach.
We use ADA4896 as a unity gain buffer amplifier. I modeled the noise of ADA4896 and see rising noise density at high frequencies. Noise density is more 6 nv/rt(Hz) above 80MHz. I noticed the same behavior in your figure. Is real ADA4896 so noisy at high…
According to the applications engineer of ADA4896, "dquiet" represents a diode that doesn't generate noise. For ADA4896, it is not relevent thus removing it won't affect the performance of the spice model.
Hope this answers…
There are 4 layers: top, gnd, power (traces, not plane), bottom. ADA4896 is on top layer. Its thermal pad connected to GND. We did not made cuts in GND plane under inverting/noninverting inputs and output of ADA4896. This is mistake and it adds some stray…
I don't see us releasing the ADA4899 in dual LFCSP in the near future. However, maybe we have a dual that can fit your application?
We recently released the ADA4896-2 and the ADA4897-2, maybe they would work for you?
