• some questions about AD8260

    Dear Sir/Madam.

    I have some questions about AD8260. I will use only the Digital VGA/Preamplifier part for AD8260.

    1.what‘s the range of the input signal and output signal?On your data sheet,

    I don’t understand the differential input signal is 2Vpp…

  • a couple of question for AD8260

    Dear Sir/Madam,

    I have a couple of question for your AD8260.

    1)

    I will just use only the high current driver part.

    Not use VGA/PreAMP and VMID buffer parts.

    If so, how should I connect the NOT USING PIN,  GND or OPEN or Pull-up high level?

    And please…

  • 关于数字VGA放大器AD8260

    您好:

    在查看AD8260时,遇到一些麻烦,请教咨询!AD8260仅使用数字VGA前置放大器。

    1、手册上在单电源3.3V,其差分输入信号是2V,这是峰峰值吗?该器件的输入信号范围是多少?

    2、差分其输出电压范围多少(峰峰值)?是根据VMDO管脚电压值定的吗?

    3、如果前置放大器电阻(RFB1、RFB2设置具体倍数,如2倍),则差分输出的最大是2 X24dB?

    4、如果不使用大电流驱动放大器,这21脚到31脚可以悬空?还有其他管脚不使用吗?管脚5 VPSB怎么配置?

    非常感谢!
