TB2912HQ

TOSHIBA Bi-CMOS Digital Integrated Circuit Silicon Monolithic TB2912HQ TB2912HQ Maximum Power 41 W BTL × 4-ch Audio Power IC The TB2912HQ is 4ch audio amplifier for car audio application. This IC can generate high power, high quality sound output, POUT MAX = 41 W, using a pure complementary P-ch and N-ch DMOS output stage. The built-in self diagnosis function which is included can be controlled via I2C BUS. In addition, stand-by and mute function, and various Protection feature are included. Features Weight: 7.7 g (typ.) High power output : POUT MAX (1) = 41 W (typ.) (VCC = 14.4 V, f = 1 kHz, JEITA max, RL = 4 Ω) : POUT MAX (2) = 37 W (typ.) (VCC = 13.7 V, f = 1 kHz, JEITA max, RL = 4 Ω) : POUT MAX (3) = 70 W (typ.) (VCC = 14.4 V, f = 1 kHz, JEITA max, RL = 2 Ω) : POUT (1) = 27 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) : POUT (3) = 46 W (typ.) (VCC = 14.4 V, f = 1 kHz, THD = 10%, RL = 2 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 stand by & muting function: controlled via I2C Bus (pin 16) Built in clipping detection (pin 4) Built in I2C Bus for stand-by, mute, voltage gain control, self diagnosis: Output short detection, offset detection, tweeter or speaker open detection (pin 22 and 25) Built-in various protection circuits (N...
