In ADA4870 datasheet, it mentioned this part could be ideal for driving high capacitive load; could you please share some idea why ADA4870 could drive high capacitive load comparing with other normal voltage feedback amplifier?


Thanks

    Hi,

    Current feedback op amps traditionally have wider bandwidths and higher slew rates than voltage feedback amplifiers. It is ideal for demanding applications that require high speed from high supply voltage at high output current. Do you have any application in mind? What type of signal are you looking to drive into what levels of capacitive load?
    

    Thanks,
    

    Kay
