Hi team,

May I know if the supply current shown below is for 1CH, or for 4CH?

Best regards,

Hello,

Thank you for your question.

This section in the datasheet applies to each channel on the device.

Hi Aaditya,

Thank you for your prompt reply. So, does that mean the value is for 1CH, or for 4CH?

For example, supply current disable at EN2=0 and Vi=Vcc1, ICC1=1.6mA max. Does that mean the supply current is 1.6mA for 1CH (so that 6.4mA max as a whole), or 1.6mA including all 4CH?

Best regards,

Kurumi

Hello,

Sorry for the confusion.

This section in the datasheet applies to each channel on the device, meaning that it is for 1 channel.

The ISO7740-Q1 has 4 channels that are individually specified in table 7.1. This means that the ICC values presented in the channel are for the 4 channels individually (ICC values are per channel).

In this example, it would be 1.6mA per channel.
