Video ICs  
4-channel PRE / REC amplifier with  
auto-tracking interface  
BA7184S  
The BA7184S is a PRE / REC amplifier developed for use in video cassette recorders. It is compatible with four-head  
decks and features built-in FB damping, four preamplifiers, a chroma output amplifier, an FM output amplifier (with  
AGC), an envelope detector and envelope comparator, a constant-current BTL-drive REC amplifier (with AGC) and  
channel switching, EP / SP switching, and mode switching integrated onto a single monolithic IC.  
Applications  
VCRs  
Features  
1) The playback amplifier has a total gain of 56dB  
(Typ.), and has a low-noise preamplifier. Designed  
for VHS band operation with low external parts  
count. The IC has 4 circuits for 4-head VCR applica-  
tions.  
4) The recording amplifier uses constant-current BLT  
drive that handles load variations (i.e. headimped-  
ance) well, and gives stable recording characteris-  
tics. 2 circuits are provided for 4-head VCR use.  
5) Built-in recording level AGC means adjustment of  
FM recording current is not necessary.  
2) Two playback output systems (through output and  
AGC output). The AGC output level is 315mVP-P  
(Typ.); suitable for FM brightness signal output.  
3) Auto-tracking interface for automated tracking  
adjustment. Linear detector characteristic with sen-  
sitivity that can be set using external components.  
6) Head switches for 4-channel PRE / REC system  
provided.  
7) Operates off a single 5V power supply, with low  
power dissipation.
