TOSHIBA Bi-CMOS Linear Integrated Circuit Silicon Monolithic
TB2929HQ
45W × 4-ch BTL Audio Power IC
The TB2929HQ 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
• POUT MAX (1) = 45 W (typ.)
(VCC = 15.2 V, f = 1 kHz, JEITA max, RL = 4 Ω)
• POUT MAX (2) = 41 W (typ.)
(VCC = 14.4 V, f = 1 kHz, JEITA max, RL = 4 Ω)
• POUT (1) = 24 W (typ.)
(VCC = 14.4 V, f = 1 kHz, THD = 10%, RL = 4 Ω)
• POUT (2) = 21 W (typ.)
(VCC = 13.2 V, f = 1 kHz, THD = 10%, RL = 4 Ω)
• Low THD: 0.007% (typ.) (VCC = 13.2 V, f = 1 kHz, POUT = 5 W, RL = 4 Ω)
• Low noise: VNO = 60 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)
• Built-in AUX amplifier from single input to 2 channels output (pin 25)
• Various protection features
Thermal overload; overvoltage; output short-circuits to GND, VCC and across the load; speaker current limiting
• Operating supply voltage: VCC (opr) = 8.0 to 18 V (RL = 4 Ω)
