Application Hints
4.2
AC-Coupled Applications
In AC-coupled applications (See
Figure 6
), only one supply (V
S
) is needed. The vertical position of
the scanning cannot be adjusted with input bias (for that purpose, usually some current is injected
or sunk with a resistor in the low side of the yoke).
4.2.1
Application Hints
Gain is defined as in the previous case:
Choose R
1
then either R
2
or R
3
. For good output centering, V
7
must fulfill the following equation:
