TREBLE AND BASS CONTROL

TWO SURROUND MODE AVAILABLE WITH

4 SELECTABLE RESPONSES:

- MUSIC

SO28

SDIP32

- SIMULATED STEREO

TWO SPEAKER ATTENUATORS:

ORDERING NUMBER: TDA7442D (SO28)

- 2 INDEPENDENT SPEAKER CONTROLS

IN 1dB STEPS FOR BALANCE FACILITY

- INDEPENDENT MUTE FUNCTION

TDA7442 (SDIP32)

ALL FUNCTIONS PROGRAMMABLE VIA SE-

RIAL BUS

2 MONITOR OUTPUT (ONLY FOR TDA7442)

grammable phase shifter. Control of all the func-

tions is accomplished by serial bus.

The AC signal setting is obtained by resistor net-

works and switches combined with operational

amplifiers.

Thanks to the BIPOLAR/CMOS Technology used,

Low Distortion, Low Noise and DC stepping are

obtained.

DESCRIPTION

The TDA7442/42D is volume tone (bass and

treble) balance (Left/Right) processors for quality

audio applications in TV and Hi-Fi systems.

It reproduces surround sound by using a pro-
