STATIC ELECTRICAL CHARACTERISTICS
Table 3. Static Electrical Characteristics (continued)
Characteristics noted under conditions 16 V ≤ B+ ≤ 34 V, 0°C ≤ T_A ≤ 70°C, and 0°C ≤ T_J ≤ 100°C unless otherwise noted.
Typical values noted reflect the approximate parameter means at T_A = 25°C under nominal conditions unless otherwise noted.

Notes
18. Errors include effects of multiplexer and sample and hold circuitry, including droop.
19. The Zero Error is defined as the number of LSB values away from the ideal value of 1/2 LSB that the ADC output count will transition
from 0 to 1 when the input is swept through the range of interest. The transition must occur within the specified range.

20. An LSB is defined as follows:
LSB = ^IMR Volts
2^#BITS -1
Where:
IMR is the Ideal Measurement Range.
#BITS is the resolution of the ADC.
21. The Full Scale Error is defined as the number of LSB values away from the ideal value of -1/2 LSB from Full Scale that the ADC output
count actually transitions from -1 LSB count to Full Scale count when the input voltage is swept through the voltage range of interest.
The transition must occur within the specified range.
