I am working on creating an high performance DC Digital Volt Meter and need help for selection the best ADC.
What is the best ADC with low noise and at lest 50sps.
And also will be good to have it able to read temperature also.
You may want to consider using AD7124 which is a newer product and has all the building blocks of AD7713 along with more filter options, 3 power modes, Reference buffers and added more advanced features such as diagnostics. Since the part operates from 2.7 to 3.6V supply, you have to design a complete analog front end solution (i.e. attenuator or voltage divider) to meet the device input specification.
