7 / 10 page Pin Descriptions (Continued) Pin 11. E-W OUT: The output waveform at this pin consists of the sum of the linear sawtooth, 2nd order parabolic and 4th order parabolic waveform components. The center posi- tion of the output waveform tracks the output voltage at pin 13 (DC OUT). See Figure 12 for the output schematic. Pin 12. C BP: A capacitor of at least 100 µF is connected from this pin to ground via a short path. Pin 13. DC OUT: This pin outputs a variable DC voltage from 3.65V to 4.05V. The output voltage is controlled by the con- trol voltage at pin 1 (POSITION). See Figure 12 for the out- put schematic. Pin 14. V CC: 12V nominal power supply pin. This pin should be decoupled to pin 6 (GND) via a short path with a capacitor of at least 100 µF. Pin 15. SAWTOOTH OUT: This pin outputs an S-corrected sawtooth waveform with the amplitude controlled by pin 2 (HEIGHT). See Figure 12 for the output schematic. Pin 16: S: A 0V to 4V DC voltage applied to this pin adjusts the amount of S correction in the sawtooth waveform at pin 15 (SAWTOOTH OUT). 0V sets maximum S correction. See Figure 13 for the input schematic. Input/Output Schematics DS012894-14 FIGURE 8. DS012894-15 FIGURE 9. DS012894-16 FIGURE 10. DS012894-17 FIGURE 11. DS012894-18 FIGURE 12.
