• RE: AD9629 Read

    Hi Doug,

    I am trying to read AD9629 and i want to ask some questions. 

    This is my circuit. Analog input range(Pin-9) of AD8475 is 0 to 4.2V. ADC inputs become 0.46V and 1.34V when AD8475 input is 0.29. And digital output of the ADC is 8D5. This value is…

  • RE: LTC6810-1

    For the funnel amplifier part, scratch the AD8475; I meant the LT1997-2.

  • RE: AFE for AD7768-4

     I know it's old, but it might be of help to others reading.

    Take a look at the AD8475.  From the datasheet:

    The AD8475 is a fully differential, attenuating amplifier with integrated precision gain resistors. It provides precision attenuation (by 0…

  • 有关AD8251芯片的压摆率和放大倍数的问题

    大家好,我想参考CN0385,设计一个18位,2MSPS数据采样系统。CN0385由AD8251和AD8475构成,带宽都满足要求,但是AD8475的压摆率在50V/us以上,而AD8251的压摆率只有20V/us。我想请问AD专家,

    1、AD8251的压摆率是指的仪表放大器输出信号的压摆率么?还是指全部输入输出的最低压摆率?因为我要采集的是差分信号,大约1MHz,峰峰值为9Vpp,最少压摆率也需要30V/us。

    2、AD有没有类似于AD825x系列的高精度、低温漂程控放大器呢?

  • AD8250 Reference Drive

    Hi All,

    I am planning to use AD8250 as a part of ADC front end along with the AD8421 and AD8475. I get what i expected from AD8421 and AD8475 but not from AD8250 so far. I use the exact differential output scheme in AD8250s datasheet (page 20). Both…

  • RE: Diffrential ADC Driver

    Hi, Vanaja.

    The recommended ADC driver for AD7175-2 is the ADA4522-2 high voltage, ultra low noise, zero drift, rail to rail output amplifier. It has peak to peak noise of 117nV and can accept a supply voltage up to +/-25V. May I know what input range are…

  • RE: How to design an ADC driver for sensing +- 10V bipolar signals and drive AD7380?

    Hi byliu

    Consider using a funnel amp like the AD8475 or the INA159 from TI.

  • RE: ADA4932-1/2 use as Funnel Amplifier.

    Hello jpearson,mle,

    Thank you for the detailed explanation.
    AD8475 will also check.

    Thank you,again.
