The TA8231LQ is BTL audio power amplifier for consumer 

application. It is designed for high power,low distortion and low 

noise. 

It contains various kind of protectors and the function of 

stand−by. 

 

Feature 

• High power 

 : POUT (1) = 42W (typ.) 

 (VCC = 14.4V, f = 1kHz, THD = 10%, RL = 2Ω) 

 : POUT (2) = 37W (typ.) 

 (VCC = 13.2V, f = 1kHz, THD = 10%, RL = 2Ω) 

 : POUT (3) = 22W (typ.) 

 (VCC = 13.2V, f = 1kHz, THD = 10%, RL = 4Ω) 

• Excellent output power bandwidth 

 : POUT (4) = 17W (typ.) 

 (VCC = 13.2V, f = 20Hz~20kHz, THD = 1%, RL = 4Ω) 

• Fixed voltage gain 

 : GV = 32dB (typ.) 

 VCC = 13.2V, Vout = 0.775Vrms (0dBm) 

• Low thermal resistance 

 : θj−c = 1.5°C / W (typ.) 

• Low distortion 

 : THD = 0.02% (typ.) 

 (VCC = 13.2V, f = 1kHz, Pout = 4W, RL = 4Ω) 

• Built−in stand−by switch function 

 : ISTBY = 100µA (typ.) 

 (With pin(1) set at high, power is turned on) 

• Built−in various protection circuit 

 : Thermal shut down,Over voltage,Out to GND,Out to VCC,Out to Out short 

• Operating supply voltage 

: VCC (opr) = 9~18V
