    AD9265与ADA4938配合是没有问题,但是AD602的-3dB带宽只有35Mhz, 所以30MHz的信号会有些衰减

  • RE: Automatic Gain Control Chip Selection


    Hi,

    Thanks for the email, I'm familiar with both of these parts. For such a low frequency application you'll need a VGA designed for dc operation. These are generally lower BW, with specified Vos numbers and dual supply. Your input range is only 80:1…

    Hi Jim, 

    I would recommend that you read the following articles that touch on programmable gain amplifiers:

    Precision Variable Gain Amplifiers

    High Speed Variable Gain Amplifiers

    A caveat to the precision VGAs is that as the configurations mostly implement…

  • Low Noise Variable Gain AD600 Amplifier

    Hello,

    I, Satyabrata Sarangi, am using AD 600 in a cascading mode to get 80 dB gain. The problem i am facing is always i am getting an amplified output, with a larger bandwidth. If the original signal is of 1 MHz, i am getting a 25-30 MHz signal as output…
