SA58632 2 × 2.2 W BTL audio amplifier Product data sheet
●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 8Ω 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.
●Features
■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 < 10μA
■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
