For measurement of the available time for load short-circuit and output noise voltage, use the specified transformer power supply shown below. The output noise voltage is represented by the peak value on rms scale (VTVM) of average value indicating type. For AC power supply, use an AC stabilized power supply (50Hz) to eliminate the effect of flicker noise in AC primary line. 40 % 20 to 50k Hz 55 kΩ 1.2 mVrms −70 0 +70 mV -2 -5 -10 V Specified Transformer Power Supply (Equivalent to RP-25) Equivalent Circuit No. 1649—2/5 STK4141V Voltage gain, VG - dB Voltage gain, VG - dB Sample Application Circuit: 25W min AF Power Amplifier (2channels) Frequency, f - Hz Output power, PO - W IC Power dissipation, Pd - W Frequency, f - Hz Input voltage, Vi - mV Output power, PO - W No. 1649—3/5 IC substrate temperature, Tc - °C Output power, PO - W Quiescent Neutral voltage, current,VIcco - mA N - mV Quiescent current, ICCO - mA Output power, PO - W Output power, PO - W Quiescent Neutral voltage, current,VIcco - mA N - mV Quiescent current, ICCO - mA Total harmonic distortion, THD - % Total harmonic distortion, THD - Hz IC Power dissipation, Pd - W STK4141V Output power, PO - W Supply voltage, VCC - V Supply voltage, VCC - V No. 1649—4/5 Output power, PO - W STK4141V Frequency, f - Hz ■ ■ No products described or contained herein are intended for use in surgical implants, life-support systems, aerospace equipment, nuclear power control systems, vehicles, disaster/crime-prevention equipment and the like, the failure of which may directly or indirectly cause injury, death or property loss.
