ANALOG_ISOLATOR_1

Published:2009/7/6 7:36:00 Author:May | From:SeekIC

Uses Mullard CNY44 opto-isolator to transmit analog signals between units of equipment having unequal ground potentials. Circuit has 3-dB roll off point at 6 Hz and 80 kHz. Total harmonic distortion at 8 V P-P out-put is less than 1.5% between 100 Hz and 20 kHz. Output transistor TR2 is not critical.- Photocouplers, Mullard, London, 1974, Technical Information 4, TP1477, p 12.
