[Required Equipment]
Power supply Stand-By Control
6Ω ( Non-inductive load )
Audio analyzer (Panasonic VP-7723B)
[Supply Voltage]
+Vcc/-Vcc : Power Supply for audio power amplifiers
Output 2 (0.4%/2Hz-20kHz)
Recommended operating
Vcc (6Ohm)
Stand-By Control (5V) : Power Supply for Stand-By Control Input
5V : Operation / 0V : Stand-by
[Operation Guide]
1. Installation of the heat sink Please refer to a thermal design tip for the amplifier.
2. Load Connection Connect the RL=6Ω (Non-inductive load)
3. Power Supply Connection Connect the +Vcc/-Vcc (Output off : 0V)
4. Stand-By Control Connection Stand-By Control = 0V : Stand-by
5. Input Connection Connect the Oscillator (Sine wave / Output resistance
600Ω)
The gain of the evaluation board is set in 30dB.
6. Power Supply At first, supply DC voltage to +Vcc and -Vcc.
Next, Stand-By Control = 5V : Operation
