另外官方资料看不到带宽增益资料，不知把mv级别的电压放大1000倍，是否可行？
Dear analog engineers,
I was looking in the datasheet of ADA4897.
There is an example of a low noise gain selectable amplifier with an extra switch in the datasheet.
In this example you placed an balance resistor, to get a more constant offset voltage…
Moving this question on amplifiers to the Amplifier community.
ADA4897-2. AD8250.
Hi ,
Could you please correct the description with regards AMP which is used for unity-gain from ADA4895-2 to ADA4897-1/ADA4898-2 on Page 17.
Thanking you
With best regards and wishes
Hi,
Thank you for reply and suggestion.
The ADA4897-2 is already evaluated but there was signal leakage from input to output when power-down was enabled. So AD8028 might be good.

Hi Fabian,
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?

I was reading the article Some Tips on Making a FETching Discrete Amplifier by George Alexandrov and Nathan Carter and was wondering about the stability of this amplifier. They make the statement "The circuit shown in Figure 2 can achieve comparable …
