Typical Performance Characteristics
The following curves apply for 12-bit + sign mode after auto-calibration with V
A
+ = V
D
+ = +3.3V, V
REF+
= +2.5V, V
REF−
= 0V, T
A
= 25°C, and f
CLK
= 6 MHz unless otherwise specified. The performance for 8-bit + sign and “watchdog” modes is equal to or
better than shown.
