I - INTRODUCTION  
tions different from the typical application diagram.  
The layout of the PCB allows thefollowing options:  
- Additionofcapacitorsin theplayback preamplifier  
section for adjusting the peaking effect in the  
frequencyresponse (C22, C23, C24, C25, C109,  
C110).  
- Implementationof an FM equalizing circuit at the  
luma output (R11, C16, L3, Q1, R12).  
- To filter the control signals(C14, C15).  
This filtering is not mandatory, however some  
usersuse it to preventthe applicationfromparasi-  
tics induced in the control wires.  
- To use only one supply line for both playbackand  
record modes (TEA5704).  
In this option the VREC line is provided from the  
VCC line through a switching circuit made by : Q2,  
Q3, R15, R16, R17, R18. The record mode is  
controlled by a signal provided at Pin Pb/REC of  
connectorJ2 (Figure 1) (L2is naturallyremoved).  
The demoboardis intended to provide theuser with  
an example of application of the SGS-THOMSON  
head amplifiers TEA5704/STV5712.  
Although the demoboard is just an example, a lot  
of care have been taken in making the layout of the  
printed copper board, and the component dimen-  
sioning.  
To better understandthe operation of the TEA5704  
and STV5712, the user can refer to the relevant  
SGS-THOMSON’s applicationnote : ”VCR Record  
and Playback Head Amplifiers” (AN445).  
Remark : The typical application diagrams given  
in this document are updated versions  
of thetypical applicationdiagramsgiven  
in the application note.

Compared with the simplest application diagram ,  
the potentiometersVR1, VR2 and VR101 have been  
added in the record signals input section in order  
to allow the user to adjust the input level at his  
convenience.
