Coupling Capacitorless Headphone Amplifiers - BD88410GUL
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 positive voltage. It is possible to drive headphones in a ground standard with both voltage of the supply voltage and the negative voltage. Therefore a large-capacity output coupling capacitor become 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. This series has a line up with the reference voltage type and the gain type.
