Typical values are at T A = 25°C and represent most likely parametric norm.
Limits are ensured to AOQL (Average Outgoing Quality Level).
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 LM89 and the thermal resistance. See () for the thermal resistance to be used in the self-heating
calculation.
This specification is provided only to indicate how often temperature data is updated. The LM89 can be read at any time without regard
to conversion state (and will yield last conversion result).
Quiescent current will not increase substantially with an SMBus.
Default values set at power up.
