AN7194K

ICs for Audio Common 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 combination 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.
