Pre Amplifier with low impedance input

Published:2013/3/12 1:34:00 Author:Ecco | Keyword: Pre Amplifier , low impedance input | From:SeekIC

Preamplifier circuit diagram shown here has a low impedance input characteristics, therefore is suitable for use with magnetic transducers: dynamic microphones, low-impedance magnetic heads, sensors phone. Amplification of this low impedance input pre amp is therefore very high, whether to reduce, there should be a trimmer R3 series to 100 ohms. The system can be powered by a voltage of between 9 and 18Volts. for its realization, follow the diagram layout.
