HA13122

      The HA13122 is a kind of dual 4 W audio power amplifier.It is specially designed for cassette radio,encapsulated in SP-15TA plastic package.It delivers 4.3 W per channel under 12 V power supply to 4 load.
      Here you can get some information about the HA13122.First is a low quiescent current (36 mA typ.) for efficient battery-operation.Besides,it is designed for low crossover distortion under a low idling current.The third one is audio muting circuit included,providing 60 dB typ of muting attenuation just by 5 mA of muting control current.Then is no electrical isolation needed for simple chasis-mounting.Furthermore,dual power amplifiers provide 4.3 W typ. under 12 V power supply voltage (R_L=4,THD=10%).The last one is internal thermal protection.
      What comes next is about the absolute maximum ratings of HA13122.The supply voltage (V_CC) is 18 V.The output current (I_O(peak)) is 4 A.The power dissipation (P_T) is 15 W.The junction temperature is 150.The operating temperature (T_opr) is from -20 to +70.The storage temperature (T_stg) is from -50 to +125.
      The following is about the electrical characteristics of HA13122(T_a=25,V_CC=12 V,R_L=4,f=1 kHz and R_g=600).The typical quiescent (I_O) is 36 mA and the maximum is 60 mA at V_in=0 V.The maximum input bias current (I_B) is 1.0A at V_in=0 V.The minimum voltage gain (G_V) is 44 dB,the typical is 46 dB and the maximum is 48 dB at V_in=46 dBm.The maximum difference of voltage gain (G_V) is ±1.5 dB at V_in=-46 dBm.The minimum output power per channel (P_out) is 3.8 W and the typical is 4.3 W at THD=10%,V_CC=12 V.The typical total harmonic distortion (THD) is 0.25% and the maximum is 1.0% at P_out=0.5 W.The typical WBN (noise output) is 0.4 mV and the maximum is 1.0 mV at R_g=10 k,BW=20 Hz to 20 kHz.The minimum supply voltage rejection ratio (SVR) is 40 dB and the typical is 44 dB at f=100 Hz,V_ripple is 0 dBm.
