1 / 12 page 1 Video ICs 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. 80VP-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. 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. •Block diagram 1 3 5 7 9 11 13 15 17 19 21 23 24 22 20 18 16 14 12 10 8 6 4 2 PB IN GND PB NFB PB EQ PB OUT PB LINE IN ALC FILTER LINE IN TUNER IN GND LINE OUT REC / EE CTRL HEAD EQ REC HSW RIPPLE FILTER VCC EQ CTRL PB / TU / EE CTRL BIAS MUTE CTRL REC NFB ALC LEVEL REC OUT REC EQ ALC – 20dB REC LINE + 20dB BA7795LS ∗ The BA7795FS has a different pin layout to the BA7795LS. |
