• 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.

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.
