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.
