Note 10: Value of acceptable cumulated parasitic load resistance due to humidity, AGC storage capacitor leakage, etc.,
for less than 1% of Vamp change.
Note 11: The threshold for VVOB is generated internally and routed to VOscF pin. Any DC current on this pin will
influence the value of VVOB.
Note 12: Maximum of deviation from an ideally linear sawtooth ramp at null SCOR (Sad09 at x0000000b) and null CCOR
(Sad0A at x1000000b). The same rate applies to V-drive signal on VOut pin.
Note 13: Maximum SCOR (Sad09 at x1111111b), null CCOR (Sad0A at x1000000b).
Note 14: Null SCOR (Sad09 at x0000000b).
Note 15: "tVR" is time from the beginning of vertical ramp of V-drive signal on VOut pin. "TVR" is duration of this ramp, see
chapter TYPICAL OUTPUT WAVEFORMS and Figure 13.
Note 16: VVOamp = VVOT -VVOB
Note 17: The same rate applies to V-drive signal on VOut pin.
Note 18: Informative, not tested on each unit.
