Product specification

Triple video output amplifier
FEATURES • Typical bandwidth of 9.0 MHz for an output signal of 60 V (p-p) • High slew rate of 1850 V/µs • No external componentsrequired • Very simple application • Single supply voltage of 200 V • Internal reference voltage of 2.5 V • Fixed gain of 51 ORDERING INFORMATION TYPE NUMBER TDA6108JF PACKAGE NAME DBS9MPF DESCRIPTION plastic DIL-bent-SIL medium power package with fin; 9 leads

TDA6108JF
• Black-Current Stabilization (BCS) circuit • Thermal protection. GENERAL DESCRIPTION The TDA6108JF includes three video outputamplifiers 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 colour CRT directly. To obtain maximum performance, the amplifier should be used with black-current control.
