Additional preview pages of the SA58637 datasheet.

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.

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.
