VCR standard audio signal processor
BA7795LS / BA7795FS
The BA7795LS and BA7795FS are standard audio signal processor ICs. They contain a playback preamplifier, line
amplifier, recoeding amplifier, ALC circuit, EQ switch circuit and high-voltage head switch, and provide all of the functions
required for normal-audio signal processing on a single IC with a minimum number of external components required.
Applications
Video cassette recorders and tape decks
Features
1) Available in compact SZIP and SSOP-A24-pin pack-
ages.
2) High-with standing-voltage head switch (AC with
standing voltage: Min. 80V
P-P
(f = 70kHz) ).
3) Simple, three-mode EQ switch built-in (BA7795LS).
4) Built-in LINE / TUNER selector switch.
5) High-performance low-noise playback amplifier.
Block diagram
Input conversion noise figure – 122dBV
(Typ. Rg = 680, DIN AUDIO).
6) ALC level can be varied.
7) ALC loop external mute eliminates audible noise at
power on, and ALC attack noise.
8) Signal processing circuit can be constructed with the
addition of just a few external components.
