I have a standard inverting amplifier stage with Rf = 100k and Rg = 10k (A = -10 V/V). The amp is powered from +/-5V and the positive input terminal is connected to 0V. Pins 1 and 5 are open. Pin 8 (nDISABLE) is also left open. Very straightforward setup…
I am using the above mentioned opamp as a unity gain amplifier and the opamp is powered from 5V supply (Single supply). I am seeing oscillations in the o/p if opamp when a dc or ac input is given to opamp. can any one suggest the reason. i have provided…
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…
可以参考一下ADA4895-1 或者 ADA4897-1 ADA4800 ADA4891-1
Question and appreciate your advise:
For a standard PCB (FR4, 4 layers 1.6mm pcb thickness, track of 0.254mm, with ground plane on the 2nd layer). point-to-point. and assuming termination is good. Signal source frequency is approx 1khz…
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.
With best regards and wishes
