• Manufacturer Part Number: STK400-020
• Description: 3-channel af Power Amplifier (15W+15W+15W)
• Manufacturer: Sanyo Semiconductor Corporation

Operating Characteristics at Ta = 25°C, R
Notes
• Use rated power supply for testing unless otherwise specified.
• When measuring permissible load short time and output noise voltage, use transformer power supply indicated below.
• Output noise voltage is represented by the peak value rms (VTVM) for mean reading. Use an AC stabilized power
