1. Where Ax=-1dB/step, Bx=-10dB/step or +2dB/step, -10dB and +2dB should not be loaded at the same time.
2. The initial condition is set to be maximum attenuation –79dB and mute on mode when the power on.
3. The output will drop down to ground gradually when enable power off preparation.
4. Odd gain 2N-1= N*(+2dB/step) + (-1dB), where N = 1~8. Please reference to examples.
