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.

Features amplifier has a total gain of 56dB

1) The playback

(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 315mV

P-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.
