LOW_NOISE_OPAMP_PREAMP

Published:2009/6/29 22:07:00 Author:May | From:SeekIC

Circuit combines noise features of discrete design with simplicity and high open-loop of IC opamp such as 741. Transistors can be 2N3708, BC109, or equivalent. Output impedance is low enough to drive headphones directly.-D. R. Hedgeland, 0p-Amp Pre-Amp, Wireless World, Dec, 1972, p 575.
