Other Parts Discussed in Thread: AFE2257,
We have signed NDA with TI and got DATASHEET. There are some questions that need to be communicated;
1. In the up and down modes, if the same charge quantity Q is input/output, is the result of AFE output the same CODE?
2. What is the input range of ADC?
3. Is the reference voltage EXCT-1 adjustable?
4. Does sampling time refer to tshs?
5. When the SR time setting range is set to the maximum, does it meet the requirements of array design?
6. Is the integral capacitance Cf of the integrator configurable, and what is the Cf range?
7. Is there only range difference between AFE2256 and AFE2257? What are the differences between the two?
8. How to configure the filter? Does the starting filter affect the charge conservation?
