Oscillator
The following basic expression for defining the oscillator frequency is valid:
f= alk
2VC
with
v=10V 2 triangular wave amplitude p - p
C = 47pF or 4.7nF or 470nF © integrating capacitor
|= 1pA...2mA ® input contro! current
The following oscillator adjustment positions are provided:
720 defining triangular wave amplitude, hence frequency also, and offset
732 defining the output square wave offset
