SA58631
3 W BTL audio amplifier
Rev. 01 — 8 March 2006
Product data sheet
1. General description
The SA58631 is a one channel audio amplifier in an HVSON8 package. It provides power
output of 3 W with an 8 Ω 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
s Low junction-to-ambient thermal resistance using exposed die attach paddle
s Gain can be fixed with external resistors from 6 dB to 30 dB
s Standby mode controlled by CMOS-compatible levels
s Low standby current < 10 µA
s No switch-on/switch-off plops
s High power supply ripple rejection: 50 dB minimum
s ElectroStatic Discharge (ESD) protection
s Output short circuit to ground protection
s Thermal shutdown protection
3. Applications
s Professional and amateur mobile radio
s Portable consumer products: toys and games
s Personal computer remote speakers
