2-channel PRE / REC amplifier with

auto-tracking interface

BA7180AS / BA7180AFS

The BA7180AS and BA7180AFS are PRE / REC amplifiers developed for use in video cassette recorders. They

have been designed for use in two-head decks and feature built-in FB damping, two preamplifiers, a chroma output

amplifier, an FM output amplifier (with AGC), an envelope detector, a constant-current BTL-drive REC amplifier (with

AGC) and built-in channel and REC / PB switches on a single monolithic IC.

Applications

•

VCRs

Features

•

4) The recording amplifier uses constant-current BLT

drive that handles load variations (i.e. head imped-

ance) well, and gives stable recording characteris-

tics. A single circuit is provided for 2-head VCR use.

5) Built-in recording level AGC means adjustment of

FM recording current is not necessary.

1) The playback amplifier has a total gain of 57dB (Typ.),

and has a low-noise preamplifier. Designed for VHS-

band operation with low external parts count.The ICs

have 2 circuits for 2-head VCR applications.

2) Two playback output systems (through output and

AGC output). The AGC output level is 300mV^P-P

(Typ.); suitable for FM brightness signal output.

3) Auto-tracking interface for automated tracking

adjustment. The detector characteristic is non-linear

to improve tracking accuracy during playback of low

signal levels.

6) Head switches for 2-channel PRE / REC system

provided.

7) Operates off a sigle 5V power supply, with low

power dissipation.
