www.DataSheet4U.com 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 s s s s s s s s 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 < 10 µA 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 3. Applications s Professional and amateur mobile radio s Portable consumer products: toys and games s Personal computer remote speakers www.DataSheet4U.com Philips Semiconductors SA58631 3 W BTL audio amplifier 4.
