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
