12.1. TDA6108JF (IC900)
12.1.1. General Description
The TDA6108JF includes three video output amplifiers in one plastic DIL-bent-SIL 9-pin medium power (DBS9MPF) package
(SOT111-1), using high-voltage DMOS technology, and is intended to drive the three cathodes of a color CRT directly. To
obtain maximum performance, the amplifier should be used with black-current control.
