KK386

      The KK386 is a kind of low voltage audio power AMP.Here you can get some information about the features.First is for battery operation.The second one is minimum external parts.The third one is wide supply voltage from 4 V  to 12 V.The fifthe one is low quiescent current drain which is 4 mA.The sixth one is voltage gains from 20 to 200.The seventh is ground referenced input.The eighth one is self-centering output quiescent voltage.The ninth one is low distortion.
      What comes next is about the maximum ratings of KK386.The V_CC (Supply Voltage) is 15 V.The V_IN (Input Voltage) is ±0.4 V.The P_D (Power Dissipation) is 1.25 W.The T_stg (Storage Temperature) is from -65 to +150.The T_J (Junction Temperature) is +150.The T_L (Lead Temperature) is +300.Then is about the recommended operating conditions.The minimum V_CC (Supply Voltage) is 4.0 V and the maximum is 12 V.The T_A (Operating Temperature, All Package Types) is from 0 to +70.
      The following is about the electrical characteristics of KK386.The minimum V⁺ (Operating Supply Voltage) is 4 V and the maximum is 12 V.The maximum I⁺ (Quiescent Current) is 8 mA at V⁺ = 6 V, V_IN = 0.The typical P_O (Output Power) is 325 mW at V⁺= 6V, R_L =8, THD=10% and is 1000 mW at V⁺= 9V, R_L =8, THD=10%.The minimum BW (Bandwidth) is 250 KHz at V⁺= 6V, Pins 1 and 8 open.The maximum THD (Total Harmonic Distortion) is 1.0% at V⁺= 6V, R_L =8, P_OUT=125mW, f=1kHz, Pins 1 and 8 Open.The typical PSRR (Power Supply Rejection Ratio) is 45 dB at V⁺= 6V, f=1kHz, C_BYPASS=10F, Pins 1 and 8 open.The minimum R_IN (Input Resistance) is 30 K and the maximum is 80 K.The typical I_B (Input Bias Current) is 250 nA at V⁺= 6V, Pins 2 and 3 open.
