PARAMETER
All parts operate properly over the 3V to 5.5V supply voltage range. The devices are tested and specified for rated
accuracy at their nominal supply voltage.
All parameters are measured at T
There is no industry-wide standard for temperature accuracy specifications. Maxim’s standard is six-sigma. The three-
sigma specification is included to allow easier comparison to products built by manufacturers who use different standards.
This specification indicates how often temperature data is updated. The devices can be read at any time without regard to
conversion state, while yielding the last conversion result.
For best accuracy, minimize output loading. Higher sink currents can affect sensor accuracy due to internal heating.
OS delay is user programmable up to 6 over-limit conversions before OS is set to minimize false tripping in noisy environ-
ments.
