1 All min and max 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.

3 Specification refers to the maximum extent of this parameter as a worst-case value at 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.
