CP-850/F Service Manual

-40-

4.8 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 colours CRT

directly. To obtain maximum performance, the amplifier should be used with black-current control.

Features

Typical bandwidth of 9.0 MHz for an output signal of 60 V(p-p)

High slew rate of 1850V/

No external components required

Very simple application

Single supply voltage of 200V

Internal reference voltage of 2.5 V

Fixed gain of 51
