Sanyo LA3220 Specifications
Any and all SANYO products described or contained herein do not have specifications that can handle
applications that require extremely high levels of reliability, such as life-support systems, aircraft’s
control systems, or other applications whose failure can be reasonably expected to result in serious
physical and/or material damage. Consult with your SANYO representative nearest you before using
any SANYO products described or contained herein in such applications.
SANYO assumes no responsibility for equipment failures that result from using products at values that
exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges,or other
parameters) listed in products specifications of any and all SANYO products described or contained
herein.
Monolithic Linear IC
2-Channel Equalizer Amplifier with ALC
Ordering number:ENN912D
LA3220
SANYO Electric Co.,Ltd. Semiconductor Company
TOKYO OFFICE Tokyo Bldg., 1-10, 1 Chome, Ueno, Taito-ku, TOKYO, 110-8534 JAPAN
Features
• Dual pre-amp with built-in ALC (pre-amp × 2 + ALC ×
2).
• Due to high gain, recording amp can be formed separately (variable monitor possible).
• ALC and direct motor drive obtained through SEPP output stage.
• Good ALC response balance between channels.
• Good reduced voltage characteristic.
• Excellent channel separation.
• Quick stabilization during power supply input.
