DESCRIPTION

Realizedwitha highvoltagebipolartechnology,the
TDA8153is a monolithic RGB video output stage
for TV color applications. It drives the CRT cath­odesdirectlyandoffersa videobandwidthcompat­ible with CCIR standards. In addition to three
independent video amplifiers, the device features
an internal generator for the first grid voltage,
flashover protection, cathode short circuit protec­tion and a commoncut-off sensing output for use
in sequentialsampling applications.

The TDA8153 is supplied in a 15 lead Multiwatt
plasticpower package.

APPLICATION NOTES
P. C. Board

The best performance of the RGB video amplifier
canbe obtainedonlywith acarefullydesignedP.C.
board. The layout of the printed circuit must be
realizedto achieve the best possible symmetry of
the three channels.

Output to input capacitances are of particular im­portance.The input-outputcapacitances,in paral­lel with the relative high feedback resistances,
createpoles in the closedloop transfer function.

To optimizethe band responseandto minimizethe
channels crosstalk a low parasitic capacitance
feedback resistors of not inductive type is neces­sary.

Capacitivecouplingfromthe output of an amplifier
and theinput ofanother onemayinduceexcessive
crosstalk.It is advisableto keep the amplifier out­puts away from amplifier inputs.

The small size of the P.C. board allows you to

mounttheTDA8153directlybesidethepicturetube
socket, to minimize the capacitances of the con­nectionsbetween the video amplifiersand the pic­ture tube cathodes.

The capacitors connectedin parallel with the input
resistorscompensate the effects of the distributed
constantsofthe printedcircuitonthe stepresponse
times. Their values must be selected on the basis
of the layout and can be consideredas function of
the printedcircuit.

The three capacitors (C9, C10, C11) between the
amplifier outputs and the feedback resistors re­duces the noise effect on the cut-off control, their
value, of course, depends on the noise amplitude
and spectrumcoming from theI.F. video stage.

To prevent possible oscillationproblems, it is nec­essarytoplacethe highvoltagefiltercapacitor(C3)
as nearas possibleto the IC groundand the latter
must be of a substantialwidth.

Power Dissipation

Taking as reference the IC internalschematic dia­gram wecan calculatethe powerdissipatedby the
videoamplifiers.
ThepowerdissipationoftheICis definedbya static

The value is reducedby 20% (0.8factor) because
duringthe flybacktime there is not signal.

The total power dissipated by the IC is therefore :
PT=PS+Pd= 1.75 + 1.90 = 3.65W

One ofthe worst workingconditionof theTVsetas
regards the power dissipation, is when you get
white noise on the screen,for example, when you
disconnect the TV aerial or the channels are not
properlytuned.

In these casesif we set the TVreceiver for 80V
