66 programmed into non-volatile on-chip registers). Temperature range is -55
68 Fahrenheit range of -67 to +257 degrees with 0.9 steps. If polarity
75 ("cooler"), vice versa. That way "heater" equals "active low", whereas
76 "conditioner" equals "active high". Please note that the DS1621 data sheet
81 of up to +/- 0.5 degrees even when compared against precise temperature
91 any of the limits have ever been met or exceeded since last power-up or
102 also pin compatible with the DS1621 and provide multi-resolution support.

113 - DS1625 - 500ms
114 - DS1631 - 93ms..750ms for 9..12 bits resolution, respectively.
115 - DS1721 - 93ms..750ms for 9..12 bits resolution, respectively.
116 - DS1731 - 93ms..750ms for 9..12 bits resolution, respectively.
119 On the DS1621, internal access to non-volatile registers may last for 10ms
