Hello,
So i need to design and make a pre- amplifier with the following specifications.
Runs on a 3.3-5 volt supply
Gain levels from 10-50dB
Must function from 5-50kHz
Low noise levels
I was wondering if anyone had any ideas of were i should start below are some of the calculations that i have done to help me select my opamps.
50dB=316.23V/V
316.23V/V x 50KHz=15.8 MHz
Now that my signal will also be filtered i know that i will need to raise it to probably around 100KHz accepted by my filter.
Thought about using an AD8099
Has a small signal bandwidth of 500MHz -Slew Rate 1.6KV/us -Vos of 200uV Noise Density of 950pV/rtHz and fits my voltage level limits
Wondering if anyone knows of how i should go about this project and picking resister and capacitor values.
