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).
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)
