15. Temperature Slope Non- linearity is measured over the specified temperature range. The actual change in output voltage is subtracted from the
expected change in output voltage, and then divided by the expected change to normalize before converting to percent.
( T S y ( Δ T ) ) – Δ VOUT
TSNL = ---------------------------------------------------------- x100%; y = 1 , 2 , 3
16. For codes n = 8 to 255
17. Guaranteed monotonic.
18. t WC is the time from a valid STOP condition at the end of a Write sequence of I 2 C serial interface, to the end of the self-timed internal nonvolatile
write cycle.
