Hi Hgtk,
The timing of Output Disable/Enable on the ADuM242E will be similar to the ADuM2402. This parameter is not tested on the ADuM242E, so it can't be specified with maximum value in the datasheet as it is for the ADuM2402.
Regards,
Jason

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…
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.

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…
Hi Rob,
The ADuM242E is indeed CMOS levels. See below for the input/output structures.
The ESD diodes should not be conducting current in normal operation. See the abs max tables for the limits on voltages at the I/O pins.

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…
