General description
The SA58631 is a one channel audio amplifier in a HVSON8 package. It provides power output of 3 W with a 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.

FEATUREs
■Low junction-to-ambient thermal resistance using exposed die attach paddle
■Gain can be fixed with external resistors from 6 dB to 30 dB
■Standby mode controlled by CMOS compatible levels
■Low standby current <10µA
■No switch-on/switch-off plops
■High power supply ripple rejection 50 dB minimum
■ElectroStatic Discharge (ESD) protection
■Output short circuit to ground protection
■Thermal shutdown protection

APPLICATIONs
■Professional and amateur mobile radio
■Portable consumer products: toys and games
■Personal computer remote speakers
