100_W_FOR_DC_TO_500_kHz

Published:2009/6/25 21:32:00 Author:Jessie | From:SeekIC

Circuit using Optical Electronics opamps has high input imped-ance, high gain capability, and 100-W output capacity without use of transformers, for highfidelity audio circuits, cathode-ray deflection circuits, and servosystems. Output currents up to 10 A require heavy output wiring, large power-supply bypass capacity, and heavy com-mon ground point. Load is in feedback loop of opamp. Constant-current drive for load makes impedance matching to loudspeaker unnecessary.- A High Gain 100 Watt Amplifier, Optical Electronics, Tucson, AZ, Application Tip 10205.
