SA58631
3 W BTL audio amplifier
Rev. 01 â 1 December 2005
Preliminary data sheet
1. General description
The SA58631 is a one channel audio amplifier in a HVSON8 package. It provides power
output of 3 W with a 8 ⦠load 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.
2. Features
â Low junction-to-ambient thermal resistance using exposed die attach paddle
â Gain can be fixed with external resistors from 6 dB to 30 dB
â Standby mode controlled by CMOS compatible levels
â Low standby current <10 µA
â No switch-on/switch-off plops
â High power supply ripple rejection 50 dB minimum
â ElectroStatic Discharge (ESD) protection
â Output short circuit to ground protection
â Thermal shutdown protection
3. Applications
â Professional and amateur mobile radio
â Portable consumer products: toys and games
â Personal computer remote speakers
