Hi,
I have questions about the LMP90077.
1. The Resolution is 16 bit, which makes 0 - 65536 values. I want to use the device single ended. Now the datasheet Figure 71 shows that the MSB seems to be reserved for the sign + or minus... Also the ADC Calcuation in 10.1.3 gives me a maximum of 32768 for VINP = 5V; VINN = 0V. Now i wonder how to measure 16bit single ended ?
2. I did some testing with the WEBENCH Designer for this chip. If gives me values of 20bits ENOB and 17.5 bits NFR. How to interpret these values?
