SUITABLE FOR HIGH DEFINITION MONI­TORS
DESCRIPTION
The TDA1170Dis a monolithicintegratedcircuitin a 16-leaddualin-line plasticpackage.Itis intended for use in black and whiteandcolourTV receivers.
Low-noise makes this deviceparticularly suit­able for use in monitors. The functions incorpo-
rated are : synchronization circuit, oscillator and ramp generator,highpower gain amplifier,flyback generator,voltageregulator.
