43.7.1 Static Performance Characteristics
In the following tables, the LSB is relative to analog scale:
Single Ended (ex: ADVREF =3.0V),
Gain = 1, LSB = (3.0V / 4096) = 732
μV
Gain = 2, LSB = (1.5V / 4096) = 366
μV
Gain = 4, LSB = (750 mV / 4096) = 183
μV
Differential (ex: ADVREF =3.0V),
Gain = 0.5, LSB = (6.0V / 4096) = 1465
μV
Gain = 1, LSB = (3.0V / 4096) = 732
μV
Gain = 2, LSB = (1.5V / 4096) = 366
