Typical Operating Characteristics
(AVDD = DVDD = +5V, external reference = +4.096V, CREF = 4.7F, CREFADJ = 0.1F, TA = +25°C, unless otherwise noted.)
Note 1: Relative accuracy is the deviation of the analog value at any code from its theoretical value after offset and gain errors have
been removed.
Note 2: Offset nulled.
Note 3: Guaranteed by design, not production tested.
Note 4: Shutdown supply currents are typically 0.5A, maximum specification is limited by automated test equipment.
Note 5: Defined as the change in positive full scale caused by a ±5% variation in the nominal supply.
Note 6: To ensure best performance, finish reading the data and wait tBR before starting a new acquisition.
TIMING CHARACTERISTICS (Figures 1 and 2) (continued)
(AVDD = +4.75V to +5.25V, DVDD = +2.7V to AVDD, external reference = +4.096V, CREF = 4.7F, CREFADJ = 0.1F, CLOAD = 20pF,
TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA= +25°C.)
