ELECTRICAL CHARACTERISTICS
Boldface limits apply over the specified temperature range, T
At T
NOTES: (1) Over-scale and under-scale complies with NAMUR NE43 recommendation. (2) Span adjustment is determined by PGA gain and sensor
excitation. (3) Span can be digitally adjusted in three ways: PGA gain, current reference Coarse, and current reference Fine. (4) RTI = Referred to Input.
(5) Current source output voltage measured with respect to I
between PGA gain steps. (8) Output current into external circuitry is limited by an external MOS power FET. (9) Measured with over- and under-scale limits
disabled.
