www.DataSheet4U.com SA58632 2 × 2.2 W BTL audio amplifier Rev. 01 — 27 June 2006 Product data sheet 1. General description The SA58632 is a two-channel audio amplifier in an HVQFN20 package. It provides power output of 2.2 W per channel with an 8 Ω load at 9 V supply. The internal circuit is comprised of two BTL (Bridge-Tied Load) amplifiers with a complementary PNP-NPN output stage and standby/mute logic. The SA58632 is housed in a 20-pin HVQFN package, which has an exposed die attach paddle enabling reduced thermal resistance and increased power dissipation. 2. Features I I I I I I I I I 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.
