Installation of the heat sink Please refer to a thermal design tip for the amplifier. 2. Load Connection Connect the RL=6 (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 600) 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 +Vcc=+27V/-Vcc=-27V V =458mVrms V =14.5Vrms(P =35W) IN O O CH1 IN CH1 OUT (CH2 IN) IF (CH2 OUT) NF 6 56k 1.8k GAIN 30dB 12/30/2013 2 www.onsemi.com
