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.

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
