Free Running Oscillator Application
Figure 54 is an EL5144 configured as a free running
oscillator. To first order, R
frequency of oscillation according to:
For rail to rail output swings, maximum frequency of
oscillation is around 15MHz. If reduced output swings are
acceptable, 25MHz can be achieved. Figure 55 shows the
