(1) Typical values are at T
A
= 25 癈 and represent most likely parametric norm.
(2) Limits are guaranteed to TI's AOQL (Average Outgoing Quality Level).
(3) The limits found in Table 1 supersede the limits shown in the Electrical Characteristics Table. The Accuracy specification includes errors
due to linearity, offset and gain. The accuracy specification includes effects of self heating with negligible digital output loading. Pull-up
resistors should be maximized (10k typical recommended), so that self heating due to digital output loading is negligible.
(4) Limits at intermediate temperatures can be calculated using a straight line interpolation as shown in Figure 2 and Figure 3.
(5) Linearity Error is defined as the worse case difference of an actual reading to that of a calculated reading derived from the straight line
whose endpoints are measured at 30癈 and 125癈 for the range of 30癈 to 125癈 or whose endpoints are measured at 30癈 and
25癈 for the range of 30癈 to 25?
(6) Offset Error calibration should be done at 30癈. The residual error of the transfer function is then equivalent to the Accuracy Limit minus
the Offset Limit. This does not take into account the power supply sensitivity of the offset error. Nor, does it take into account the error
introduced by the calibration system used.
(7) This specification is provided only to indicate how often temperature data is updated. The LM92 can be read at any time without regard
to conversion state (and will yield last conversion result). If a conversion is in process it will be interrupted and restarted after the end of
the read.
(8) 12 bits + sign, two's complement
(9) Default values set at power up.
