ā—¸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 ...
