ZoomingADC for sensing data acquisition
Revision 1.01
January 2011

In "continuous-time" mode, the input signal is repeatedly converted into digital. After a conversion is finished, a new
one is automatically initiated. The new value is then written in the result register, and the corresponding internal
trigger pulse is generated. This operation is sketched in Figure 17. The conversion time in this case is defined as TCONV.
In the "on-request" mode, the internal behavior of the converter is the same as in the "continuous-time" mode, but the
conversion is initiated on user request (with the Start bit). As shown in Figure 18, the conversion time is also TCONV.
7.7.8 Output Code Format
The ADC output code is a 16-bit word in two's complement format (see Table 19). For input voltages outside the range,
the output code is saturated to the closest full-scale value (i.e. 0x7FFF or 0x8000). For resolutions smaller than 16 bits,
the non-significant bits are forced to the values shown in Table 20. The output code, expressed in LSBs, corresponds to:
Recalling Equation 10, page 25, this can be rewritten as:
