Note 4:
All parts operate properly over the +VS = 3V to 5V supply voltage range. The devices are tested and specified for rated
accuracy at their nominal supply voltage. Accuracy typically degrades 1°C per volt of change in +VS as it varies from the
nominal value.
Note 5:
All parameters are measured at +25°C. Values over the temperature range are guaranteed by design.
Note 6:
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.
Note 7:
For best accuracy, minimize output loading. Higher sink currents can affect sensor accuracy due to internal heating.
Note 8:
OS delay is user programmable up to six “over-limit” conversions before OS is set to minimize false tripping in noisy
environments.
Note 9:
Default values set at power-up.
Note 10:
All timing specifications are guaranteed by design.
Note 11:
A master device must provide a hold time of at least 300ns for the SDA signal to bridge the undefined region of SCL’s
falling edge.
Note 12:
CB = total capacitance of one bus line in pF. Tested with CB = 400pF.
Note 13:
Input filters on SDA, SCL, and A_ suppress noise spikes less than 50ns.
Note 14:
Holding the SDA line low for a time greater than tTIMEOUT causes the devices to reset SDA to the IDLE state of the serial
bus communication (SDA set high).
ELECTRICAL CHARACTERISTICS (continued)
(+VS = +3.0V to +5.5V, TA = -55
°C to +125°C, unless otherwise noted. Typical values are at +VS = +5V, TA = +25°C.) (Notes 4, 5)
