STV9302A

Application Hints

The yoke can be coupled either in AC or DC.

4.1

DC-coupled Application

When DC coupled (see Figure 4), the display vertical position can be adjusted with input bias. On

the other hand, 2 supply sources (VS and -VEE) are required.

A Stand-by state will be reached by switching OFF the positive supply alone. In this state, where

both inputs are the same voltage as pin 2 or higher, the output will sink negligible current from the

deviation coil.

4.1.1

Application Hints

For calculations, treat the IC as an op-amp, where the feedback loop maintains V1 = V7.
