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

Notes
14. Errors include effects of multiplexer and sample and hold circuitry, including droop.
15. The Linearity Error is the worst case error caused by the differential and integral nonlinearity.
16. An LSB (least significant bit) is defined as follows:
IMR
Volts
LSB =
2#BITS-1
Where:
IMR is the Ideal Measurement Range.
#BITS is the resolution of the ADC.
17. The ADC will read full scale at V = 5.0 V. If V on one input exceeds this value, the value of other inputs may become unreadable.
