Other Parts Discussed in Thread: ADS1115

Hello,

My customer uses the ADS1115, measure single-ended signal.

He wants to know how about the Cross Talk characteristics from AN0 to AN1.

Could you tell me the Cross Talk level?

Regards,

Naoki Aoyama

    Naoki-san,


    The cross talk level on this device should be very small. I don't have any specific data on this particular device, but on other 24-bit precision data converters from this group, the cross talk has been measured with AC and DC signals and found to be at the level of the ADC noise.

    Since the ADS1115 is a 16-bit converter, any cross talk should be at least an order of magnitude lower than the LSB resolution and not measurable by the ADC.
