Then, S and C correction shapes can be added to this ramp. This frequency independent S and C corrections are
generated internally. Their amplitude are adjustable by their respective I
2
C register. They can also be inhibited by
their select bit. Endly, the amplitude of this S and C corrected ramp can be adjusted by the vertical ramp amplitude
control register. The adjusted ramp is available on pin 23 (VOUT) to drive an external power stage. The gain of this
stage is typically 25% depending on its register value. The mean value of this ramp is driven by its own I

C register
(vertical position). Its value is VPOS = 7/16

±
300mV.
Usually VOUT is sent through a resistive divider to the inverting input of the booster. Since VPOS derives from
V
REF-V
, the bias voltage sent to the non-inverting input of booster should also derive from V
REF-V
to optimize the
accuracy(see Application Diagram).
Basic Equations
In first approximation, the amplitude of the ramp on pin 23 (Vout) is:

= V22 ( ramp with fixed amplitude)
- VAMP = - 1 for minimum vertical amplitude register value and +1 for maximum
- VPOS is calculated by : VPOS = V
