LTC1821
Note 8: To 0.0015% for a full-scale change, measured from the rising
edge of LD.
Note 9: REF = 0V. DAC register contents changed from all 0s to all 1s or all
1s to all 0s. LD low and WR high.
Note 10: Midscale transition code: 0111 1111 1111 1111 to
1000 0000 0000 0000. Unipolar mode, CFEEDBACK = 33pF.
Note 11: R1 and R2 are measured between R1 and RCOM, REF and RCOM.
Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2:
±1LSB = ±0.0015% of full scale = ±15.3ppm of full scale.
Note 3: Using internal feedback resistor.
Note 4: Guaranteed by design, not subject to test.
Note 5: IOUT with DAC register loaded to all 0s.
Note 6: Typical temperature coefficient is 100ppm/
°C.
Note 7: Measured in unipolar mode.
