hi,
At present, ADS1263 is selected. Some questions need to be consulted:
1. Does the chip have to support differential?
2. What is the role of the third pin AINCOM, how to use it?
3. Is there a crystal oscillator of the 15th and 16th crystal oscillator pins that can only be connected to the MCU? If it can be connected to an external crystal oscillator, what's the difference between using crystal oscillator of MCU?
Our demand is: the analog acquisition voltage value is our power supply voltage, which is initially determined to be 5V, 3.3V, 1.3V, multi-channel acquisition, 32-bit high precision, because MCU resources are limited, so try to occupy as little as possible The resources of the MCU.
Can the chip meet the requirements?
thanks.
