all 1s to all 0s. LD high, WR and MLBYTE pulsed.

(J/°K), R = resistance (Ω), T = temperature (°K), B = bandwidth (Hz).

Note 12: Midscale transition code 0111 1111 1111 1111 to

1000 0000 0000 0000.

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 6: Typical temperature coefficient is 100ppm/°C.

Note 8: To 0.0015% for a full-scale change, measured from the falling

edge of LD.
