adxl362功耗大 0
Not Answered

同一批 SMT 焊接出来板子，ADXL362 功耗全部偏大；把这批坏的芯片拆下来，换上之前老批次芯片，同一块 PCB、同样程序，功耗立刻恢复正常，这个能确认是这批芯片质量问题吗？芯片都是在同一家经销商购买的，有没有可能是焊接问题，要求的焊接温度是怎样的？我这个原理图是这样的，看看合理吗需要修改吗？

ADIS16507-2 标定后零偏稳定性明显高于数据手册典型值 0
Not Answered

您好，我们正在评估 ADIS16507-2（陀螺仪量程 ±500°/s，加速度计量程 ±40 g），并计算了零偏稳定性,发现零偏稳定性远大于手册所写。当前器件及驱动配置如下： 1.使用内部时钟，输出数据速率为 2000 SPS，不进行抽取； 2.上电并执行硬件复位后，设置 FILT_CTRL = 0x0003 ，即 Bartlett 滤波器 B = 3，陀螺仪和加速度计的数字带宽约为 80 Hz； 2.MSC_CTRL 仅使能 BURST32 ，采用32位突发读取； 4.其余配置保持出厂默认值...

ADXL356BEZ使用故障 0
Answered

ADXL356BEZ 加速度计，装在产品上出现的故障现象，放在平板上动一下倾角再放平，显示的值回不到原来的零位值了，把这个焊下来换一个新的就正常了，目前装了150片，发现了6片这样的，见视频，请问这可能是什么原因造成的呢？

这个描述的意思是 X轴数据高位只用了4bit，低位也只用了4bit的意思吗？但是为啥说是12位？

ADXL357，Y轴出现异常； 0
Answered

ADXL357测量Z、Y两个方向的振动加速度，STM32通过SPI读取后，再通过DAC输出两个通道值：0g时输出5V，+0.5g输出10V，-0.5g输出0V； ①0g加速度时，通道Z输出正常，DAC保持输出5V±0.001V。通道Y输出异常，DAC电压从 5V±0.001V 缓慢下降至4.95V后，再恢复到5V，见下图； ②上图中加了高通，纵轴换算成了加速度g，也就是缓慢负向变动了约50mg； ③出现上述异常的概率较低，不容易复现。硬件上，两个通道的处理方式一模一样； ④STM32主控...

当设置ODR=3200HZ，用做检测±1g的振动G值，从振动频率只有400HZ时测量值就开始衰减是符合滤波的衰减曲线的吗
