Description
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.
Features
• 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)
