    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.
