AN5829S

Sound multiplex decoder IC for the U.S. televisions

■ Overview

The AN5829S is a multiplex sound demodulation IC dedicated to the U.S. television and incorporates a bidirectional I2C interface (adjustment, mode SW), an AGC circuit and external stereo input switches (2 systems).

■ Features

•Stereo demodulation, SAP demodulation, dbx noise reduction, AGC, external stereo input SW and I2C bus interface are integrated in a single chip

•Bi-directional I2C bus makes it possible to monitor MPX input level, separation adjustment (3 places), mode changeover and receiving status.

•Eliminated external parts (multi-sound block: 21 pieces → 14 pieces

•Lower power dissipation (VCC = 5 V, ITOT = 18 mA)

■ Applications

• Televisions and VCRs for the North American market
