Shutdown
I Shutdown mode control signal input, place entire IC in shutdown mode when
held high, Idd=0.7uA
I Gain select input pin, logic high will switch the amplifier to external gain
mode, and logic low will switch to internal unity gain.
I Mode select input pin, fixed gain when logic L and gain adjustable mode
when logic H.
I Mute control input pin, active H.
