• RE: ADL5380-EVALZ DC IF Problem

    Hi Eric,

    Currently, the only software available specifically geared towards the AD7903 is the customer evaluation software that is associated with the AD7903 SDP-compatible evaluation board.  There are many devices in the ADI SAR ADC portfolio that have…

  • Error reading data of the AD7903

    I'm using AD7903,Read data using FPGA from the ad7903. Use the  CS Mode, 3-Wire Interface Without Busy Indicator.Reading data is always 0x8000.this is why?

  • AD7903 problem.

    Hi all,

    i'm using the AD7903 ADC in the CS Mode, 4 Wire interface without busy indicator.

    the differential input voltage is 3.6[V], and when im trying to read the ADC number, it simply doesnt work. im always getting random numbers that have no…

  • RE: 求推荐AD和采样芯片

    AD7903可以实现同步采样,

    对于1M采样率 , 5M带宽, AD7903可以完成相关工作

    以下链接中有, 带隔离的ADC,可以参考一下

  • SAR ADC能使用更低的参考电压吗?

    我想使用AD8338 直接驱动AD7903,AD8338输出是正负1.4V,AD7903的REF范围是2.4V 至 5V,我如果用2.5V基准会损失0.8位精度,能否使用1.8的基准,会产生什么后果?

  • AD7903 calculate LSB

    Hello,

    the question is about the AD7903 http://www.analog.com/static/imported-files/data_sheets/AD7903.pdf

    I have calculate the LSB with

    u_LSB = u_in / 2^n

    The input voltage (full scale) is u_in = +-5V when Ref=5V and resolution of 16 Bit.

    => u_LSB…

  • AD7903 Simultaneous Sampling

    Hello,

    I want to use the AD7903 in the way of Simultaneous Sampling. But Im not sure, how connect them with the SPI interface.
