Headphone Amplifiers Coupling Capacitorless Headphone Amplifiers BD88200GUL,BD88210GUL,BD88215GUL,BD88220GUL No.11102EAT05 ●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.
