• AD7416: Ambient temperature and PCB temperature

    As an Reliability Engineer, I need a temperature model of the AD7416 internal
    temp. sensor, which is coupled by an specific RTH to the PCB and by another to
    the ambient cooling air. The reason is to know, which temperature is measure,
  • Does the AD7416 setpoint registers with 10 MSB or 9 MSB? And what is the default value? Seems the datasheet conflict itself.

    On the datasheet it said temperature value register is 10 MSB, however OTI and HYST setpoint register is 9 MSB. As I assume this is right. 

    As shown below OTI setpoint register default is 80.

    And HYST setpoint register default is 75.

    Later in the…

    Dear Sirs,

    we're searching for a digital temperature sensore (on the i2c bus) to be used with BF537 and uClinux last release.

    Could you suggest something that is…

  • ADC 分辨率和精度的区别

    分辨率和精度这两个,经常拿在一起说,才接触的时候经常混为一谈。对于ADC来说,这两样也是非常重要的参数,往往也决定了芯片价格,显然,我们都清楚同一个系列,16位AD一般比12位AD价格贵,但是同样是12位AD,不同厂商间又以什么参数区分性能呢?性能往往决定价格,那么什么参数对价格影响较大呢?不好意思,我其实还是有些迷惑的,但是看了下篇文章,至少知道“精度”是有很大影响力的。该篇文章主要解释ADC分辨率和精度的区别,非常详细且易懂,值得一看,全文如下:
