TOSHIBA Bi-CMOS Digital Integrated Circuit
Silicon Monolithic
TB2904HQ
Maximum Power 43 W BTL
× 4-ch Audio Power IC
The TB2904HQ 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.
Additionally, Off-set detector is built in.
Features
High power output
: POUT MAX (1) = 43 W (typ.)
P (VCC = 14.4 V, f = 1 kHz, JEITA max, RL = 4 )
: POUT MAX (2) = 39 W (typ.)
(VCC = 13.7 V, f = 1 kHz, JEITA max, RL = 4 )
: POUT (1) = 26 W (typ.)
(VCC = 14.4 V, f = 1 kHz, THD = 10%, RL = 4 )
: POUT (2) = 23 W (typ.)
(VCC = 13.2 V, f = 1 kHz, THD = 10%, RL = 4 )
Low distortion ratio: THD = 0.015% (typ.)
(VCC = 13.2 V, f = 1 kHz, POUT = 5 W, RL = 4 )
Low noise: VNO = 90 Vrms (typ.)
(VCC = 13.2 V, Rg = 0 , BW = 20 Hz to 20 kHz, RL = 4 )
Built-in standby switch function (pin 4)
Built-in muting function (pin 22)
Built-in Off-set detection function (pin 25)
Built-in various protection circuits:
Thermal shut down, overvoltage, out to GND, out to VCC, out to out short, speaker burned
Operating supply voltage: VCC (opr) = 9 to 18 V (RL = 4 )
Note 1: Since this device’s pins have a low withstanding voltage, please handle it with care.
Note 2: Install the product correctly. Otherwise, it may result in break down, damage and/or degradation to the
product or equipment.
Note 3: These protection functions are intended to avoid some output short circuits or other abnormal conditions
temporarily. These protect functions do not warrant to prevent the IC from being damaged.
In case of the product would be operated with exceeded guaranteed operating ranges, these protection
features may not operate and some output short circuits may result in the IC being damaged.
Weight: 7.7 g (typ.)
