UP_TO_1OO_kHz_WITH_322_TIMER

Published:2009/7/2 1:07:00 Author:May | From:SeekIC

Efficient LC oscillator uses IC timer as inverting comparator, with pinetwork LC tank as resonant circuit. Output square wave is regulated to 3 V in amplitude, independently of supply voltage; upper supply limit should be 40 V instead of value shown. Sine-wave output of oscillator may also be used extemally by adding single-supply opamp as buffer. Values shown give 10 kHz, but upper limit is 100 kHz.-W. G.
