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 comprised of two Bridge-Tied Load (BTL) amplifiers with a complementary PNP-NPN output stage and standby/mute logic. The SA58637 is housed in a 20-pin HVQFN package, which has an exposed die a.
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 dB I Standby mode controlled by CMOS-compatible levels I Low standby current < 10 µA I No switch-on/switch-off plops I High power supply ripple rejection: 50 dB minimum I ElectroStatic Discharge (ESD) protection I Output short circuit to ground protection I Thermal shutdown protection 3. Applications I Professional and amateur mobile radio I Portable consumer products: toys and games I Personal computer remote speakers NXP Semiconductors SA58637 2 × 2.2 W BT.
