The TB2936HQ 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 49 W. It includes a standby switch, mute function and various
protection features.

BTL stands for “Bridge-Tied Load,” and a BTL power amplifier is a type of audio amplifier configuration used to drive a load, such as a speaker or a transducer, in a way that maximizes power transfer and output without the need for a center-tapped transformer. BTL amplifiers are commonly used in audio applications where increased power output is required, such as in car audio systems and high-power home audio amplifiers.



• High output power

• POUT MAX (1) = 49 W (typ.)
(VCC = 15.2 V, f = 1 kHz, JEITA max, RL = 4 Ω)

• POUT MAX (2) = 43W (typ.)
(VCC = 14.4 V, f = 1 kHz, JEITA max, RL = 4 Ω)

• POUT (1) = 26 W (typ.)
(VCC = 14.4 V, f = 1 kHz, THD = 10%, RL = 4 Ω)

• POUT (2) = 23 W (typ.)
(VCC = 13.2 V, f = 1 kHz, THD = 10%, RL = 4 Ω)

• Low THD: 0.015% (typ.) (VCC = 13.2 V, f = 1 kHz, POUT = 5 W, RL = 4 Ω)

• Low noise: VNO = 160 μVrms (typ.)
(VCC = 13.2 V, Rg = 0 Ω, BW = 20 Hz to 20 kHz, RL = 4 Ω)

• Standby switch (pin 4)

• Mute function (pin 22)

• Output DC offset detection and clip detection (pin 25)

• Various protection feature
