AFE7901: Leaving DAC unused

Ernest Yong

Part Number: AFE7901

Tool/software:

Hi Team,

if customer will use ADC (Tx) in AFE7901 and leave the DAC pins (Rx) unused then will this add any noise into the system?

Hi Ernest,

No. When the TX channels are not used these should be connected to 1.8V and disabled in the configuration using the "sysParams.txEnable = [False,False,False,False]" parameter.

Best,

Camilo
