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 O 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.
- 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
