Hi
Could anybody refer me to a relatively inexspensive low noise preamplifier for ultrasonic application?
The source is capacitive with the real portion of the impedance arround 15k ohms.
The amplifer should have 40-60dB of gain, I am expecting signals of order of 1uV.
I also would need anti-aliasing filters with a cut-off at 500kHz along with this amplifier.
Is there anything I can buy off the shelf? I need many at least two dozen of channels so it should be relatively compact.
thanks
