Notes:
4. All outputs unloaded.
5. 0.1Hz to 10Hz. PSRR at 60 Hz will exceed 120 dB due to the benefit of the digital filter.
6. In unipolar mode the offset can have a negative value (-VREF) such that the unipolar mode can mimic
bipolar mode operation.
7. The specifications for Input Overrange and for Input Span apply additional constraints on the offset
calibration range.
8. For Unipolar mode, Input Span is the difference between full scale and zero scale. For Bipolar mode,
Input Span is the difference between positive and negative full scale points. When using less than
the maximum input span, the span range may be placed anywhere within the range of ±(VREF + 0.1).
Specifications are subject to change without notice.
