AD7768单次模式下是否可以通过控制start信号周期从而控制采样率 0
Answered

AD7768单次模式使用不太清楚，对于AD7768单次模式，我是不是可以通过控制start信号（MCU输出一个PWM信号给start信号），进而产生周期性的SYNC_OUT信号（SYNC_IN与SYNC_OUT已经短接），从而控制AD7768的采样率，如果可以的话那寄存器配置中的抽取率如何设置呢？如果不可以的话，单次模式如何正确使用？

ADC芯片电源供电要求（AD7689） +1
Answered

AD7689 的 DATASHEET上描述，产品为单电源供电，范围为2.3V到5.5V，那是否意味着，我的电源可以在2.3到5.5V任意波动呢，如果不能，这个说明的含义是什么呢

AD转换过程中的采样周期和采样窗口是什么关系？ 0
Not Answered

在AD转换过程中的四步中，采样保持转换编码，采样周期是每个开关过程所经历的时间，是用sin(x)/x这样的函数去触发开关管，那么采样窗口是什么意思，和采样周期之间有什么区别？采样窗口是保持电路中的开关两次相邻动作所需要的时间吗？采样窗口是如何影响采样带宽的，能否给出实际电路分析采样窗口对采样带宽的影响作用？

ad7606的问题 0

我手里有一批使用ad7606的通信板，有一部分无法与7606通信，通过mcu的代码发现busy一直为高，还有一部分通信成功但是采集到的数据有几十mV的偏差因为使用的mcu和代码都是一样的怀疑是硬件上的问题，但是通信板也是一样的不知道哪些部品可能出问题。我用万用表量了电压，通信成功但是有误差的板子上AGND = 0V REFOUT = 2.48V AVCC = 4.97V REFCAPA REFCAPB = 4.5V 没误差的反而 AGND = 3V REFOUT = 4V 而无法通信的AGND在2V...

AD421在有仿真器的条件下同样的程序输出电流正常，移除仿真器设备供电，设置电流永远大于20毫安 +1
Answered

我用的MSP430F149通过IO口连接AD421,在使用仿真器调试时，输出电流和设置电流一致，但移除仿真器后，电流无论如何都大于20毫安。代码相同，供电部分用示波器监测电压也是稳定的。LATCH,CLK,DATA三个引脚的发送波形周期和幅度也没有变化。其他外设如EEPROM和LCD的SPI通讯都正常，就AD421输出异常。代码完全一样，有无仿真器就不同结果。
