Low frequency oscillator circuit with TcA580

Published:2012/8/22 20:18:00 Author:Ecco | Keyword: Low frequency , oscillator | From:SeekIC

In order to use TCA580 as oscillator, the circuit must connect an external circuit for attenuation, then the loop - oscillation loop's quality factor becomes infinite or negative. In the circuit shown as the figure, when emitter current IE =1.6mA, internal resistance of T4 tube re= 16Ω.
