General 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).
