TB2901H
Maximum Power 47 W BTL × 4-ch Audio Power IC
TB2901H
The TB2901H is 4-ch BTL audio amplifier for car audio
applications.
This IC can generate higher power: POUT MAX = 47 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, high-side switch is built in.
