HARD_LIMITING_OPAMP

Published:2009/7/13 21:25:00 Author:May | From:SeekIC

Based on limited output swing of opamp. Single pot adjusts both positive and negative limit points. First opamp produces limiting. Second opamp serves as voltage follower for isolating attenuator and redueing output impedance. Matching of output between limit points is within about 100 mV at output level of 2 V P-P. Opamps specified are adequate for 3-kHz bandwidth.-E. E. Bames, Ease Hard-Limiter Design with Op Amps, EDN Magazine, Aug. 5, 1975, p 76.
