BA7795中文资料罗姆数据手册PDF规格书

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.

• Features

1) Available in compact SZIP and SSOP-A24-pin packages.

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.

• Applications

Video cassette recorders and tape decks
