Product Information

INTEGRATED CIRCUITS DATA SHEET TDA6108JF Triple video output amplifier Product specification Supersedes data of 1998 Jun 22 File under Integrated Circuits, IC02 1999 Oct 29 Philips Semiconductors 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 components required • 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 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 colour CRT directly. To obtain maximum performance, the amplifier should be used with black-current control.
