SA58631TK

3 W BTL音频放大器 3 W BTL audio amplifier

General description

The SA58631 is a one channel audio amplifier in an HVSON8 package. It provides power output of 3 W with an 8Ωload at 9 V supply. The internal circuit is comprised of a BTL Bridge Tied Load amplifier with a complementary PNP-NPN output stage and standby/mute logic. The SA58631 is housed in an 8-pin HVSON package which has an exposed die attach paddle enabling reduced thermal resistance and increased power

dissipation.
