In the following tables, the LSB is relative to analog scale:
Table 40-30. Gain Error, 12-bit Mode, VDDIN 2.4V to 3.6V supply voltage conditions
• Single Ended (ex: ADVREF=3.0V),
• Differential (ex: ADVREF=3.0V),
– Gain = 1, LSB = (3.0V / 4096) = 732uV
– Gain = 2, LSB = (1.5V / 4096) = 366uV
– Gain = 4, LSB = (750mV / 4096) = 183uV
– Gain = 0.5, LSB = (6.0V / 4096) = 1465uV
– Gain = 1, LSB = (3.0V / 4096) = 732uV
Gain = 4, LSB = (750mV / 4096) = 366uV
