TB2912HQ
Overview
- 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 (Note 1, Note 2) Thermal shut down, over-voltage, out to GND, out to VCC, out to out short circuit
- Operating supply voltage: VCC (opr) = 9 to 18 V (RL = 4 Ω) VCC (opr) = 9 to 16 V (RL = 2 Ω) Note 1: Install the product correctly. Otherwise, it may result in break down, damage and/or degradation to the product or equipment. Note 2: These protection functions are intended to avoid some output short circuits or other abnormal conditions temporarily. These pr
