Video ICs  
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 300mVP-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.
