M7612
1. The output impedance is approximately 32Ω. Therefore, to ensure output matching, connect an external resistor
2. Connect a distortion meter to the output, and input a f = 1kHz sine wave. Adjust the input level until the output
3. Input a 1V
4. Input a 1V
5. Input 1V
6. Input a 1V
The frequency characteristic is given by G
of 43Ω.
CTL pin voltage at which the V
distortion is 0.5%. This output voltage at this time multiplied by 2 is the maximum output level V
