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 = TJ = TMIN to TMAX; all other limits TA = +25°C; unless

otherwise noted. TD is the junction temperature of the remote thermal diode. TJ is the junction temperature of the LM96063.

“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 LM96063 and the thermal resistance. See Note 4 in the Absolute Maximum Ratings table for the

thermal resistance to be used in the self-heating calculation.
