LAC673 is a single chip stereo paly integrated circuit which is produced by MITSVMI, it is widely used in import radio walkman. 1. LAC673 internal block and pin function LAC673 integrated circuit contains double preamplifier, double power amplifier, DC electronic volume control circuit, DC motor steady speed circuit. The internal circuit block diagram of this integrated block is shown in the figure1. This IC adopts dual flat type package, the pin function and data of this integrated circuit is shown in the table1. 2. LAC673 typical application circuit Because LAC673 integrated block is functionally complete, it can form a stereo tape player circuit with a LAC673, if adding a stereo tuner then it can form a stereo radio player circuit. The typical application circuit of LAC673 integrated block is shown in the figure1. The figure1 is the internal circuit block diagram of LAC673 integrated block The table1 is the pin function and data of LAC673 integrated circuit The figure1 is the typical application circuit of LAC673 integrated block
