SA58637
Datasheet
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 Ohm 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 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 < 10 uA
- 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
