single point ground. The transistor and 5k potentiometer are used to sample the oscillator waveform and apply an
adjustable ramp to pin 3.
Figure 4 is the basic test circuit for AP384XC. In testing, the high peak currents associated with capacitive loads
necessitate careful grounding techniques. Timing and bypass capacitors should be connected close to pin 5 in a
