AUTO_RADIO_AMPLIFIER

Published:2009/6/28 23:29:00 Author:May

Circuit shown per-mits operation of Slgnetics NE540 power driver front single-polarity 12-V supply of auto. Bipolar supplies for differential inputs of 540 are achieved by returning inputs to half of available supply or 6 V. Load is AC coupled because am piif et has DC gain of 1, and amplifier output is therefore 6 VDC. 39-ohm supply resistors are selected for minimum crossover distortion.- Signetics Analog Data Manual, Signetics, Sunnyvale, CA, 1977, p 764.   (View)
