SA58637 - 2 x 2.2W BTL audio amplifier
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.
