• ADXL325如何正确使用问题

    本人用ADXL325芯片测量加速度,将3V直流电压加到VSS和ST引脚端,COM口接地,Y轴输出端直接到示波器上显示输出波形,本人不断将芯片沿着Y轴方向不断来回移动,可始终没有产生信号,都是噪声。是什么哪个步骤做错了吗?求专业人士指导,谢谢

  • ADXL325 vibration bias

    I am currently using the ADXL325 sensor to measure the acceleration normal to the ground of a moving vehicle (using Y-axis, facing downward) and have noticed a bias which occurs when the vehicle increases speed.

    Attached is a plot of G vs seconds illustrating…

  • ADXL377 Damping factor

    Hi,

    Could you please tell me what the typical damping factor is for the ADXL377 accelerometer?

    I seen a similar post to mine was answered but for the ADXL325 and ADXL326  accelerometers, in that answer it was said them accelerometers have an under-damped response…

  • How to treat out-of-spec acceleration measurements

    I am using a ADXL325 accelerometer to measure vibration of a moving vehicle, and have been getting acceleration values above the nominal ±6g range.  They are sporadic and are likely not critical to the overall measurement, but I am wondering what I should…

  • RE: ADXL320JCP停产证明

    现在仍在量产中,将来可能停产,推荐使用ADXL325.

    产品在停产前,会在网站上有last buy的信息。

  • RE: ADXL327 COM Pins

    Hi,

    We use three accelerometers of ADXL327, ADXL325 and ADXL326 which are mounted closely and

    only ADXL327 happens in no moving condition.

    The device have operated for 3 months normally then happened in the market.

    2 of over 250 sets happened but…

  • lower ADXRS620 output impedance , higher ADC accuracy ?

    Hi

    I use LTC1408 (ADC) to convert ADXL325 and ADXRS620 analog signals. LTC1408 ask to use a buffer amplifier before ADC to transform the analog signals, which have high source impedance.

    ADXL325 has an output impedance of 32k for LP filter, so it is…

  • RE: Accelerometer Damping Factor ?

    Hi Nick100,

    The mechanical sensor in these products (ADXL325/326) has an under-damped response with a Q of ~4.5.  However, the signal conditioning ASIC has a -3dB corner frequency of 1600Hz and is a single pole filter.  So for frequencies below 250Hz the…
