Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for

which the device is functional, but do not ensure performance limits. For ensured specifications and test conditions, see the Electrical

Characteristics. The ensured specifications apply only for the test conditions listed. Some performance characteristics may degrade

when the device is not operated under the listed test conditions.

(2)

All voltages are measured with respect to GND, unless otherwise noted.

DC ELECTRICAL CHARACTERISTICS

TEMPERATURE-TO-DIGITAL CONVERTER CHARACTERISTICS

The following specifications apply for VDD = 3.0 VDC to 3.6 VDC, and all analog source impedance RS = 50Ω unless

otherwise specified in the conditions. Boldface limits apply for TA = TMIN to TMAX; all other limits TA = +25°C.

“Typicals” are at TA = 25°C and represent most likely parametric norm. They are to be used as general reference values not for critical

design calculations.

(2)

Limits are specified to AOQL (Average Outgoing Quality Level).

(3)

Local temperature accuracy does not include the effects of self-heating. The rise in temperature due to self-heating is the product of the

internal power dissipation of the LM63 and the thermal resistance. For the thermal resistance to be used in the self-heating calculation,

see the table footnote about Thermal resistance junction-to-ambient.

(4)

Thermal resistance junction-to-ambient when attached to a printed circuit board with 2 oz. foil is 168°C/W.
