The circuit diagram below appears CA3130 test circuit amplifier which is used for wideband noise measurement service. It results in 30dB gain for its output.
CA3130 test circuit amplifier is operated at a total supply voltage of
15V in the low-noise performance considerations. It shows how versatile
of this CA3130 in applications where source resistance of the input
signal is on the order of 1MOhms or more.
