1 All minimum and maximum specifications are guaranteed. Typical specifications are not tested or guaranteed.
2 Dynamic range is the maximum full-scale measurement range possible, including output swing range, initial offset, sensitivity, offset drift, and sensitivity drift at
5 V supplies.
3 Specification refers to the maximum extent of this parameter as a worst-case value of TMIN or TMAX.
4 Frequency at which response is 3 dB down from dc response with specified compensation capacitor value. Internal pole forming resistor is 180 kΩ. See the Setting
Bandwidth section.
5 Self-test response varies with temperature. See the Self-Test Function section for details.
