The
range.
Note 1: Absolute Maximum Values are those beyond which the life of a
device may be impaired.
Note 2: 1LSB = 0.006% of full scale = 61ppm of full scale for the
LTC1591/LTC1591-1. 1LSB = 0.0015% of full scale = 15.3ppm of full
scale for the LTC1597/LTC1597-1.
Note 3: Using internal feedback resistor.
Note 4: Guaranteed by design, not subject to test.
Note 5: I
Note 6: Typical temperature coefficient is 100ppm/ C.
Note 7: I
Note 8: To 0.006% for a full-scale change, measured from the rising edge
of LD for the LTC1591/LTC1591-1. To 0.0015% for a full-scale change,
measured from the rising edge of LD for the LTC1597/LTC1597-1.
