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.
