Part Number: ADS1015


Hi team，

Confirm two simple pieces of information:
(1) Whether the detection voltage range of the chip is the following information？


(2) Is there flag bit for 12bit data?

    Hi Alan,

    Alan Xia said:
    (1) Whether the detection voltage range of the chip is the following information？

    Yes, those are the input voltage ranges the ADS1015 can support. The full-scale range is configured by bits PGA[2:0] in the Config register and can be set to ±6.144 V, ±4.096 V, ±2.048 V, ±1.024 V, ±0.512 V, ±0.256 V.

    Single-ended input voltage signals can range from 0 V up to positive supply or +FS, whichever is lower. Negative voltages cannot be applied to these devices because the ADS1015 can only accept positive voltages with respect to ground. The ADS1015 offers a differential input voltage range of ±FSR. Single-ended configurations use only one-half of the full-scale input voltage range.

    (2) Is there flag bit for 12bit data?

    The ADS1015 features a programmable digital comparator that can issue an alert on the ALERT/RDY pin. 

    The ALERT/RDY pin can also be configured as a conversion ready pin. 

    Hope this information helps. 

    Best Regards,

    Angel
