TB2926HQ  -  45 W × 4-ch BTL Audio Power IC  -  TOSHIBA Corporation  -  Audio Power Amplifier

The TB2926HQ is a four-channel BTL power amplifier for car audio applications.
This IC has a pure complementary P-ch and N-ch DMOS output stage, offering maximum output power (POUT MAX) of 45 W.
It includes a standby switch, mute function and various protection features.

Features
• High output power
