• RE: AD717x, external C is required when Internal REF is enable

    Hi Akihiko,

    Yes you are correct.

    With REFBUF enabled, the buffers provide the benefit of giving the user high input impedance and allow high impedance external sources to be directly connected to the reference inputs. But when using external references…

  • AD7176-2 REFOUT while using an external reference

    Hi,

    I am designing a board to read +-10V signals using the AD7176-2. I want to drive it by a AD8475 as on page 24, but to be able to use a single 5V supply, I will use an ADR444 supplying 4.096V as an external reference.

    Now I am unsure about the state…

    The AD7768/AD7768-4 24 bit sigma delta ADC offers multiple power modes and decimation rates for scaling both power and bandwidth. There is also the option to use sinc or wideband filters and turn on or off analog pre-charge buffers, among many other configurable…

  • AD7685 4 LSB bit are 1111 (or may be 0000)

    Hello all,

    I'm using the 3 AD7685 converters in chain mode without busy indicator (mode described in datasheet on p.22 )  and I'm having a problem with one of it.

    The first converter in chain does not work properly. The 4 LSB bit are constant…

  • 最新方案文档推荐——医疗X射线成像解决方案

    医疗X射线成像检查的目的是识别病人身体中的异常情况或将病人归类为健康人群,同时最大程度地降低辐射影响。数字X射线(DR)和计算机断层扫描(CT)是最常用的X射线成像技术和应用。

    医疗X射线成像原理和典型架构

    DR和CT的基本工作原理相同:X射线束穿过人体,一部分X射线由内部结构吸收或散射,余下的X射线图案传输到检测器,用于电路和计算机进行记录或进一步处理。

    DR检测器:DR检测器包括闪烁晶体层、TFT面板、模拟数据采集系统和数字处理系统。闪烁晶体层将X射线光子转换为可见光子,TFT面板将可见光子转换为电子…

  • AD7765的数据输出口SDO输出全是1怎么办

    按照芯片资料写的读时序函数,但不知为什么数据输出全是1,是不是得先对AD控制寄存器进行写操作?

    用示波器测得读时序和SDO电平如下图

  • Max-Min ripple required for ADC AD7764

    I wanted to know what is the maximum and minimum ripple required for the voltage pins AVDD1 and DVDD. We are trying to give 2.5V from the switch mode power supply but the AVDD1 pin is connected to the modulator.

    Kindly reply.
