NOTES:
6. Typical values are for T_A = +25°C and 12V supply voltage.
7. LSB: [VDAC₂₅₅ – VDAC₀]/255. VDAC₂₅₅ and VDAC₀ are the DAC output voltage when DAC register set to FF hex and 00 hex
respectively.
8. DNL = [VDAC_i – VDAC_i-1]/LSB-1, for i = 1 to 255. i is the DAC register setting.
9. INL = [VDAC_i – (i • LSB + VDAC₀)]/LSB for i = 1 to 255.

for i = 1 to 255 decimal, T = -40°C to +125°C, referenced to 40°C.
11. Limits established by characterization and are not production tested.
12. t_WC is the time from a valid STOP condition at the end of a Write sequence of a I²C serial interface Write operation, to the
end of the self-timed internal non-volatile write cycle. The Busy Polling method can be used to determine the end of the
non-volatile write cycle.
13. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established
by characterization and are not production tested.
14. B_25/85 is a thermistor material specific constant; represents the slope of the Resistance vs. Temperature curve.
