i have a question on the bandwidth in GAIN=20 become my design is on the high frequency application of INA217.
The datasheet said the Bandwidth is 3,4 MHz when G=1, and 0.8 MHz when G=100.
But it do not tell the bandwidth when G=20.
Who can tell me how to get the value?
Hi Zhimin,
As Kai suggested, you may estimate it from the captured figure 1 below. I do not see the pspice simulation in this part, otherwise, you may find the answer via a simulation.
With Gains = 20V/V, which is 20log(20) = 26dB. based on the Figure 1, the BW of INA217 at 26dB is approx. 2MHz range (maybe slightly less) at -3dB point.
If you have additional questions, please let us know.
Best,
Raymond
