Audio ICs

Dual preamplifier with ALC

BA3308 / BA3308F / BA3308FV

The BA3308, BA3308F and BA3308FV are dual preamplifier ICs with built-in ALC circuits, and have been designed for

use in stereo radio-cassette recorders and tape recorders. They come in compact 9-pin SIP (BA3308), 14-pin MF

(BA3308F) and 14-pin SSOP (BS3308FV) packages, and have two record/playback preamplifiers, and an ALC circuit.

Thepreamplifiershavehighgainandlowdistortion, andcanbedirectlycoupledtothetapeheadwithoutcouplingcapaci-

tors. This prevents tape head magnetization and “pop” noise generation.

A built-in rectifier means that an ALC circuit with good channel balance and large dynamic range can be constructed

with addition of just an external time constant circuit.

The ICs also include power-on mute circuits that suppress “pop” noise generation.

FApplications

Stereo radio cassette recorders, cassette decks and

home stereo systems and music centers

FFeatures

1) Built-in ALC rectifier diode.

2) Wide operating power supply voltage range (V^CC=

4.5V to 14V).

6) Low noise (V^NIN= 1µVrms)

7) Input coupling capacitors and not necessary.

8) Good ALC channel balance.

3) Low current dissipation (I^Q= 3.5mV).

4) High gain (G^VO= 80dB).

9) Power-on mute circuit.

10) ALC dynamic range can be varied by the addition

of an external input resistor.

5) Low distortion (THD = 0.1%).

FAbsolute maximum ratings (Ta = 25_C)

FRecommended operating conditions (Ta = 25_C)
