ISOLATION_WITH_GAIN_COMPENSATION

Published:2009/7/6 7:32:00 Author:May | From:SeekIC

Provides total harmonic distortion under 1% while automatically adjusting for temperature-produced or other DC gain variations in opto-isolator. Output signal is sampled and fed back to FET to maintain constant AC gain. Design equations are given.-A. Billings, Optocoupler Provides Analog Isolation, EDN Magazine, Nov. 5, 1978, p 121-122.
