SA58637 Datasheet | NXP Semiconductors

2 × 2.2 W BTL audio amplifier Rev. 01 - 25 February 2008 Product data sheet 1. General description The SA58637 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 prised of two Bridge-Tied Load (BTL) amplifiers with a plementary PNP-NPN output stage and standby/mute logic. The SA58637 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 Low junction-to-ambient thermal resistance using exposed die attach paddle I Gain can be fixed with external resistors from 6 dB to 30...
