SA58632
1. 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 8 Ω 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.
2. Features

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
3. Applications
Professional and amateur mobile radio
Portable consumer products: toys and games
Personal computer remote speakers
