• ADuM2402 & ADuM242

    2402 C grade can not support 75MHz square waveform.

    242 we tested is okay. Could you help us to explain the relationships between bps and Hz? Thank you very much.

  • ADuM242E Output Disable/Enable Propagation Delay

    Hi

    Our customer will use ADuM242E.

    Is it possible to tell me the Output Disable/Enable Propagation Delay specification?

    Because ADuM242E datasheet does not say this parameter but other product, for example ADuM2402, describes its parameter in the datasheet…

  • 数字隔离器ADUM242E输出包含1kHz的低频纹波

    采样方案为Isolated ADC + Digital Isolator+模拟滤波器(三阶RC滤波),两级隔离,Digital Isolator选用ADUM242E,传递10M的数据流,模拟滤波器对Digital Isolator的输出信号进行滤波,截止频率30kHz,输出波形中存在40mV左右的1kHz的纹波,对Digital Isolator的输出信号使用示波器上的滤波器滤波,也可以看到相同频率和赋值的纹波,不知道为什么数字隔离器输出的数据流中会包含这种频率的成分,而隔离ADC输出也即数字隔离器输入…

  • RE: Supply current required(approximate values of Idd1 and Idd2) for ADUM242E when there is no input and Vdd1 and Vdd2 are 3.3 V

    Hi,

    The ADuM242E is an On-Off Keying (OOK) architecture. It transmits a signal across the barrier in its non-default state. It more or less sits idle in the default state. See the figure 19 and Figure 20 in the ADuM242E datasheet. 

    If we look at the ADuM242E0…

  • Quiescent supply current for ADuM24xE

    Hello,

    I have two questions about quiescent supply current for ADuM240E/ADuM241E.

    Q1. Are the test conditions correct ?

        The quiescent supply currents are indicated in table1 and table3 which are printed in datasheet. Idd1 and Idd2 have two current…
