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。

    • BD8878FV-EVK-001
    • 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.
