Hello-
We use an ADR430B as the external reference. This device has an external trim adjust pin. The datasheet shows how to connect this to a pot for adjustment. We have been considering some possible circuits which would measure the temperature…
I cannot seem to find any reference on AD's website for small part markings.
I have some ADR430ARZ chips but I am trying to decipher the date code. Is anyone able to tell me what the markings on the top and bottom of my chip are? Some are obvious…
Hi Neil,
many thanks for your prompt answer. Please find attached the schematic.
I need to acquire a +/-1V signal and for this reason I have setup the pair of resistor dividers respectively at the non-inverting (8) and REF (2) pins of the ADA4941-1…
这个芯片(AD9833)的名字我猜的,可忽略看,如果是这个芯片,左看右看也不知是干吗呢?
看看截图：
Hello ERussell,
The minimum voltage you can set on the reference terminal is 0.8V above the negative supply. This would explain the behavior you are observing.
I can think of two options for you:
1. You can increase your reference level. However,…
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…
