CP-093F Service Manual
5.4 TDA6107AJF
The TDA6107AJF includes three video output amplifiers and is intended to drive the three
cathodes of a colour CRT directly. The device is contained in a plastic DIL-bent-SIL 9-pin
medium power(DBS9MPF) package, and uses high-voltage DMOS technology.
To obtain maximum performance, the amplifier should be used with black-current control.
