ZoomingADC for sensing data acquisition

Revision 1.0

February 2011

As already mentioned, NELCONV must be equal or greater than 2 to reduce internal amplifier offsets.

7.7.5 Resolution

The theoretical resolution of the ADC, without considering thermal noise, is given by:

Using look-up Table 16 or the graph plotted in Figure 13, resolution can be set between 6 and 16 bits. Notice that,

because of 16-bit register use for the ADC output, practical resolution is limited to 16 bits, i.e. n = 16. Even if the
