Monolithic Linear IC
LA7415
VHS VCR Playback Head and Record Amplifiers
Overview
The LA7415 is a record and playback amplifier IC for
VHS format VCR decks. In combination with a Sanyo
LC7420 or LA7430 Series video signal processing IC, the
LA7415 can provide an adjustment-free Y/C record
current.
Features
• Record amplifier: Provides stable recording
characteristics using a fixed-current drive technique that
is resistant to load variations.
• REC-AMP: Includes a built-in AGC circuit.
• Can use the same printed circuit board as the LA7411.

Notes 3. Measure with a DC voltage of about 1.8 V applied to the AGC detector filter pin (pin 12) and with the AGC amplifier gain fixed.
4. Adjust the output level by applying a DC voltage to T13 (REC CUR.Adj2)
5. Use a resistor with a ±1.0% tolerance between pins 14 and 15.
