BD8878FV
無需耦合電容的線路放大器
BD8878FV是無需輸出耦合電容的線路放大器。內建負電源發生電路。通過採用正電壓與負電壓的兩種電壓來驅動線路放大器，以ground level為基准進行輸出。因此，具有廣闊的輸出動態範圍，可利用5V的單電源輸出2Vrms的訊號。由此，可減少高電壓輸出的穩壓器。此外，因為是以ground為基准進行輸出，無需輸出耦合電容即可連接其他元件。

BD8876FV, BD8878FV are output coupling capacitor-less line amplifiers. These 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.
