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.

BD8878FV is output coupling capacitor-less line amplifiers. This IC have a negative voltage generator built-in and generate the negative voltage from the supply voltage. It is possible to drive in a ground reference with both voltage of the supply voltage and the negative voltage. Therefore, these line amplifiers have wide output range, and BD8878FV can output 2Vrms(5.65VP-P) with the single-supply 5V.

ROHM's high efficiency step-down switching regulator BD8966FVM / 8964FVM / 8963EFJ / 8960NV is a power supply designed to produce a low voltage including 1 volts from 5.5 / 3.3 volts power supply line. Offers high efficiency with synchronous rectifier. Employs a current mode control system to provide faster transient response to sudden change in load.
