TB2904HQ - Maximum Power 43W BTL 4-ch Audio Power-IC
is made only on the single channel) 1.
Voltage Gain Adjustment This IC has no NF (negative feedback) Pins.
Therefore, the voltage gain can not be adjusted, but it makes the device a space and total costs saver.

TB2904HQ(o) TOSHIBA Bi-CMOS Digital Integrated Circuit Silicon Monolithic TB2904HQ (o) Maximum Power 43 W BTL × 4-ch Audio Power IC The TB2904H (o) 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.
