TB2904HQ

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. 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 Ω) : POUT MAX (2) = 39 W (typ.) (VCC = 13.7 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 distortion ratio: THD = 0.015% (typ.) (VCC = 13.2 V, f = 1 kHz, POUT = 5 W, RL = 4 Ω) Low noise: VNO = 90 µVrms (typ.) (VCC = 13.2 V, Rg = 0 Ω, BW = 20 Hz to 20 kHz, RL = 4 Ω) Built-in standby switch function (pin 4) Built-in muting function (pin 22) Built-in Off-set detection function (pin 25) Weight: 7.7 g (typ.) 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 Ω) Note 1: Since this device’s pins have a low withstanding voltage, please handle it with care.
