Product data sheet
1. General description
The SA58631 is a one channel audio amplier 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) amplier 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.
