TB2905HQ規(guī)格書詳情
The TB2905HQ is a high-efficiency class KB power amplifier IC developed for car audio applications that incorporates four BTL amplifier channels.
It employs a pure complementary DMOS output stage consisting of P-ch upper and N-ch lower sections, offering a maximum output power (POUT) of 47 W. Class KB (keyed BTL) amplifiers exhibit less than half the heat generation of comparable class AB solutions under normal operating conditions. Therefore, it is possible to design a smaller heatsink and maintain lower internal temperature in the car audio sets.
Features
? High output power
: POUT MAX (1) = 47 W (typ.)

: POUT MAX (2) = 43 W (typ.)
(VCC = 13.7 V, f = 1 kHz, JEITA max, RL = 4 ?)
: POUT Pout MAX (3) = 80 W (typ.)
(VCC = 14.4V, f = 1 kHz, JEITA max, RL = 2 ?)
: POUT (1) = 29 W (typ.)
(VCC = 14.4 V, f = 1 kHz, THD = 10, RL = 4 ?)
: POUT (2) = 25 W (typ.)
(VCC = 13.2 V, f = 1 kHz, THD = 10, RL = 4 ?)
: POUT (3) = 55 W (typ.)
(VCC = 14.4 V, f = 1 kHz, THD = 10,RL = 2 ?)
? Low distortion ratio
: THD = 0.03 (typ.)
(VCC = 13.2 V, f = 1 kHz, GV = 26dB, POUT = 2 W, RL = 4 ?)
? Low noise
: VNO = 120 μVrms (typ.)
(VCC = 13.2 V, GV = 26dB, Rg = 0 ?, BW = 20 Hz~20 kHz, RL = 4 ?)
? Built-in standby (pin 4) and muting (pin22) functions
? Built-in offset/clipping detection (pin 25)
? Protective circuits: Thermal shutdown, overvoltage, out to GND, out to VCC, out to out short
? Operating supply voltage: VCC (opr) = 9 to 18 V (RL = 4 ?)
