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.
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.
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.
6) Head switches for 4-channel PRE / REC system
provided.
7) Operates off a single 5V power supply, with low
power dissipation.
