Description  
BD88xxxGUL is output coupling capacitorless headphone amplifier. This IC has a negative voltage generator of regulated  
type built-in and generates the direct regulated negative voltage from the supply voltage. It is possible to drive headphones  
in a ground standard with both voltage of the positive voltage (+2.4V) and the negative voltage (-2.4V). Therefore a  
large-capacity output coupling capacitor becomes needless and can reduce a cost, a board area, and the height of the part.  
In addition, there is not the signal decrement by the low range to happen by output coupling capacitor and output load  
impedance and can output a rich low tone.  
And, the function “Virtual ground” is embedded. Noise between IC and Headphone jack can be canceled by using “Virtual  
ground” function.
