Hi all,

I am to use the AD9219 quad ADC in a new design.

I will use only three of the four ADCs and I would like to turn the fourth in power down mode.

The datasheet rev. E is not clear to me, it seems programming the 0x22 register could do the job, but there is only one register and it is not dedicated to any channel...

Could anyone help me ?

Thanx,

Mathieu

Hi Mathieu,

You can use register 0x05 device_index_A to select the channel you want to power down. Please keep in mind that every time you want to write to a different channel, this register needs to be updated.

Hope this helps.

Judy
