Maximum Power 43 W BTL x 4-ch Audio Power IC

The TB2906HQ is 4-ch BTL audio amplifier for car audio applications.
This IC can generate higher power: POUT MAX = 43 W as it includes the pure complementary P-ch and N-ch DMOS output stage.
It is designed to yield low distortion ratio for 4-ch BTL audio power amplifier, built-in standby function, muting function, and various kinds of protectors. Additionally, Off-set detector is built in.
