Overview
The LA70001 and LA70001M ICs provide record and
playback amplifiers for VHS format VCRs. A system with
an adjustment-free Y/C record current can be achieved by
combining the LA70001/M with an LA71000M or
LA71500M video signal processing IC.
Features
Direct connection of the head to the playback amplifier
input allows the number of external devices to be
reduced.
A fixed-current drive technique that is strongly resistant
to load fluctuations is adopted in the record amplifier for
stable recording characteristics. The record amplifier
includes a built-in AGC circuit.
These products have the same package dimensions as
the LA70011 and LA70011M to allow a common PCB
to be used. These products can also share the same PCB
with the LA70020 by mounting the IC at the right end of
the LA70020 socket.
