Note:
• All capacitors are in μ F unless otherwise noted. (p: pF) 50
WV or less are not indicated except for electrolytics and
tantalums.
• All resistors are in Ω and 1/4 W or less unless otherwise
speci fi ed.
• f : Internal component.

).
Voltage variations may be noted due to normal production
tolerances.
• Waveforms are taken with a oscilloscope.
