A general-purpose preamplifier has been developed to complement a wide range of measurement transducers, being particularly well suited for use with subminiature condenser microphones. The miniaturized preamplifier configuration has exzcellent performance characteristics with regard to self-noise, frequency response, dynamic range, input impedance, and low power consumption.
