ADC solution suggestion...

Other Parts Discussed in Thread: ADS1115

Dears,

I need to find an ADC for my 0~0.5V signal input.

Is there any suitable ADC solution suggestion.

The speed and interface are not key points to care.

Thanks.

    Peter,

    There are a lot of differentiating features for ADCs, It would help to have at least a little information about the resolution, data rate, input range and accuracy that you are looking for. Also, it helps to know if you are primarily looking at DC or AC measurements.


    However, if you're looking for a generic ADC, I think the ADS1115 is a rather good choice. It's a 16-bit ADC with a programmable data rate from 8 to 860 samples per second. It comes with an internal reference, and has a programmable gain so you can select one of six gain ranges. It uses I2C for communications. Again look through the datasheet to make sure it's suitable for your needs.
