Oscillator Section
Oscillator Frequency vs Timing Resistance
Maximum Duty Cycle vs Timing Resistor
High peak currents associated with capacitive loads necessi-
tate careful grounding techniques. Timing and bypass capaci-
tors should be connected close to pin 5 in a single point
ground. The transistor and 5k potentiometer are used to sam-
ple the oscillator waveform and apply an adjustable ramp to
pin 3.
