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
