Other Parts Discussed in Thread: ADS1220

Hello TI team,

I think to use ADS1220 one of my project. But i had a question,

I have two different analog inputs, one of them is PT100 (RTD-4Wire) and the other one is single-ended analog input. May I connect these analog inputs with one ADS1220?

    Hi Bekir,

    Welcome to the forum! Yes, you can connect both a 4-wire RTD and a single-ended input to the ADS1220 at the same time.  In the most current ADS1220 datasheet, you can use figure 79 on page 54 as a guide. Notice that AIN2 is unconnected in the figure.  This input can be used for your single-ended measurement.

    Best regards,
