February 24, Embedded Staff Confused by analog-to-digital converter specifications? Although manufacturers use common terms to describe analog-to-digital converters ADCs , the way ADC makers specify the performance of ADCs in data sheets can be confusing, especially for a newcomers. ADC measurements deviate from the ideal due to variations in the manufacturing process common to all integrated circuits ICs and through various sources of inaccuracy in the analog-to-digital conversion process. ADC performance specifications are generally categorized in two ways: DC accuracy and dynamic performance.

I went through the manual, it says in the differential mode it will work as 15 bit ADC. If anybody worked on this microcontroller, please tell me how to get the sign bit.?
How am I supposed to write to an datwsheet within the scratchpad memory when the input to the write function is of type UINT, which means I datashert only go as high as 0xFFFF, range from 0 to? What more do you want? What is the relation to from linear address to device address? Thanks for your help. So the 16th bit will give idea about the sign of the bit. I really dont know which controller you are talking about.
Replied Jun But the datasheet says that the output xf is in 15bits for a differential mode. But I am talking about 16 bit ADC in differential mode. I am unable to get a solution what will be the output if the differential voltage is negative, since in my application both positive and negative voltage may come in the input.
Neil Posted 5-Jul Thanks for quick reply. If you got an idea please inform me. So I think the 16th bit will be used as the sign bit.
