ADC Key Parameters
Table 10-6 describes the key ADC parameters measured at 25°C and VDD_PADS at 3.0 V, for a sampling clock
of 1 MHz. The single-ended measurements were done at f
1.2 V p-p swing). The differential measurements were done at f
scale is a 2.4 V p-p swing) and a common mode voltage of 0.6 V.

(from single-cycle test)
the input buffer is not selected. VGND cannot be measured when the input buffer is enabled because it is
outside the buffer’s input range.
N
16-bit two’s complement 32767 as the conversion result. Instead, VREF yields a value close to 8192.
N
Offset correction is affected by the gain correction value. Offset correction is calculated after gain
correction has been applied.
VREF
VREF/2
is a sampling of VREF. Due to the ADC's internal design, VREF does not yield the maximum positive
is a sampling of VREF/2. VREF/2 yields a value close to 0.
