• 关于AD5398输出电流值的问题

    您好!电路如下,目前问题是通过I2C设置1个AD值,LED就可以点亮,但是之前设置小于10个AD值基本就不会亮了,现在已经排除LED的变异,对于芯片焊接也反复做过验证,基本可以排除。请问还存在哪些可变因素导致这样的现象?

    如下是LED手册:

  • 关于AD5398的线性度

    您好!请问手册中这句话的意思是线性度是在32至1023AD值范围内测试的吗?那是不是小于32AD值就无法保证线性度呢?如果长期使用小于32AD值的输出电流,稳定性如何?

  • RE: AD5398A vs AD5821A

    Hi,

    In terms of specs both parts AD5398A and AD5821A are nearly the same.

     

    One of the main differences is the XSTHUTDOWN pin in AD5398A is active low and PD pin in AD5821A is active high. 

     

    Also, the I2C address range for the AD5398 goes from 0x18 to 0x1F…

    AD5398, 120mA Current sinking DAC With Reduced Current Range

    I'm working with the AD5398. I don't need the full 120mA range of the device.  Is it possible to get the full 10bit resolution over a smaller current range, say 20mA?   What would be the…
