Video ICs  
2-channel PRE / REC amplifier with  
auto-tracking interface  
BA7181FS  
The BA7181FS is a PRE / REC amplifier developed for use in video cassette recorders. It has been designed for use  
in two-head decks and features 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 chan-  
nel and REC / PB switches on a single monolithic IC.  
Applications  
•
VCRs  
Features  
•
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 IC has two circuits for two-head VCR  
applications.  
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 two-head VCR  
use.  
2) Two playback output systems (through output and  
AGC output). The AGC output level is 300mVP-P(Typ.);  
suitable for FM brightness signal output.  
5) Built-in recording level AGC means adjustment of  
FM recording current is not necessary.  
6) Head switches for two-channel PRE / REC system  
provided.  
3) Auto-tracking interface is provided for automated  
tracking adjustment. The detector characteristic is  
linear, and the sensitivity can be adjusted using  
external components.  
7) Operates off a single 5V power supply, with low  
power dissipation.
