Overview: ICs for Audio mon Use AN7194K, AN7194Z
Dual BTL 50 W single power supply class-H power amplifier IC
s Overview
The AN7194K and AN7194Z are single power supply, BTL, audio class-H power amplifier ICs. A class-H power amplifier can be made up when this ICs are used in bination with the AN7077Z which is separately market-available, and it is possible to make a low consumption power system. Also, the AN7194K and AN7194Z are incorporating various protection circuits, so that those ICs contribute to the high reliability design of set. AN7194K
