ADS1114: ADC recommendation inquiry

JH Shin

Part Number: ADS1114

Hello,

My customer is looking for two ADCs as shown below.

Could you please recommend two ADCs with the following conditions?

1. 1CH ADC

    - Resolution = 10Bits or more, Input = single-ended or both(differential, single-ended) support, Digital I/F = I2C (with I2C address selection)

2. 6CH or more ADC

    - Resolution = 10Bits or more, Input = both(differential, single-ended) support, Digital I/F = I2C (with I2C address selection)

Thank you.

JH

    Hello JH,

    1. The ADS1114 is a great device as you noted. If looking for a lower resolution device, the ADS1014 , which is a 12 bit version. i did a quick parametric search for your criteria with a result of 9 devices ~click here~

    2. With such little information, i cannot make a device recommendation, but a parametric search resulted in 8 devices ~click here~ that may be on interest

    Hope this helps,

    Cynthia

    Hi Cynthia,

    Thanks for your help.

    I am not sure about the conditions below for the 8 devices recommended for ADCs over 6CH.

     - Resolution = 10Bits or more, Input = both(differential, single-ended) support, Digital I/F = I2C (with I2C address selection)

    I believe that only the three devices below meet all conditions. Am I right?

    Regards,

    JH

    JH,

    Unfortunately not, the three devices you are looking at are Pseudo differential, which is closer to single ended than a differential ADC. 

    I don't believe we have a device that has all the criteria asking for, which is why knowing what the application or use case is to recommend better fitting devices. 

    This result show 9 devices that are differential and I2C, but have 4 channels

    Regards
