• AD4003 Conversion result

    Hello

    Please let me know your advice about the output timing  of AD4003 conversion result.

    Below is the timing chart of turbo mode at the datasheet P.29 figure 55.

    I thought that the result from below conversion means below D17:D0 at the timing chart 

  • spi code for ad4003

  • AD4003 Quiet Time

    In the datasheet for the AD4003, there is a 190ns quiet time as soon as the CNV signal is high.  Is this the time that the capacitors(Vref/2, Vref/4, Vref/8,...,Vref262,144) are being switched and the digital value is being generated in the Control Logic…

  • AD4007 / AD4003 - TIA interface

    Hello,

    we are looking into a transimpedance amplifier frontend based on the AD8597 for the AD4007 (or the AD4003).

    Is it feasible to use the AD8597 as a buffer for the SAR ADC ?

    Would there be any drawbacks compared to the suggested ADA4897 in the…

  • Strange Data Glitch on AD4003 FMC on ZC706

    Hello,

    We noticed a strange data glitch on the AD4003 running the evaluation FMC card - shown below. Captured conditions were CNV rate of 1.6 MSPS and SCK rate of 80 MHz using VIO = 2.5V.  We've changed the timing of our signals (CNV, SCK) and tried VIO…

  • dsp的硬件spi怎么驱动AD4003

    我有用到ad4003,用dsp的硬件spi驱动的,可是硬件spi的时序是固定的,没办法实现datasheet中的时序,也没找到单片机驱动ad4003的例程,可以提供参考么

  • What is full input voltage range on AD4003 in differential mode?

    Looking at the datasheet for the AD4003, it implies you can have an Analog Input Voltage Range from -Vref to +Vref. Therefore, you can have a -5 to +5V input. Is that correct?

    Thank you,

    Chris

  • AD4003使用一段时间后噪声变大

    问题描述:

           按照AD4003芯片手册和评估板参考电路,设计并制作PCB板。使用FPGA驱动AD4003读取数据,未使用turbo模式,采样速率800KHz。电路板上电后,将模拟输入接地,采集对地噪声信号。AD4003正常工作时,噪声峰峰值约为0.8mV(输入电压范围±5V)。使用一段时间或开关电路板几次后,采集到的数据噪声会变得很大,噪声峰峰值约为60mV(输入电压范围±5V)。但是AD4003还能正常采集信号,从FPGA读出的数据是连续的,没有跳跃点,只是波动变大了…

  • 关于AD4003基准输入的缓冲器供电电压

    我想为AD4003提供5V基准电压,但AD4003手册中基准输入引脚最大耐压为6V,我该如何设置基准缓冲运放的电源电压?

    目前电源轨有+5V和±15V,+5V为基准缓冲器供电肯定是不行的,但是使用±15V为基准缓冲器供电又担心如果上电故障会损坏AD4003。

    AD4003手册中给出了基准电压为5V的典型配置,标注的电源电压为≥6.5V,但未标明基准缓冲器电源电压。

    请问如何为基准缓冲器选择电源电压可以提供5V基准,又不会有损坏AD4003的风险?
