AN7351K, AN7351SC
Dual Pre-Amplifier ICs for Hi-Fi Cassette Deck
s Overview
The AN7351K and the AN7351SC are the single chip
ICs designed for pre-amp. for stereo cassette (double
deck especially) incorporating 2-ch rec./playback/line
amp. and muting/switching circuits.
s Features
• Available for double deck
1. Available for playback amp. tape speed switching
2. Available for rec. amp. mute function
3. Available for playback amp. input and output switch-
ing function
• Rec. amp. current and voltage both drive output is pos-
sible.
• Line amp. + mute circuit built-in
• Playback equalizer switching built-in
• Available for microcomputer direct drive of switching
