The SA58631 is a one channel audio amplifier in an HVSON8 package. It provides poweroutput of 3 W with an 8 W 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.
The document describes the NXP SA58631, a single-channel Bridge Tied Load (BTL) audio amplifier housed in an 8-pin HVSON package. It is designed to deliver up to 3 W of output power into an 8 Ω load at a 9 V supply voltage.
