how to process unused AIN pin of ADS1015

Other Parts Discussed in Thread: ADS1015

Hi,

I am trying to use ADS1015 for my design, but i only required to use 3 AIN for ADC process, as ADS1015 have 4 AIN input pin, now my question is how to process that unused AIN pin, just keeping it open or pull down it to GND or pull up to VCC through a weak resistor?

Thank you

Hello TieXue,

Thank you for your query. I would have the unused inputs connected to a known voltage within the supply range. For simplicity, I would recommend connecting to either GND or VDD whichever option is convenient.

Thanks,
Krunal
