Note 6:
All part numbers of the LM75 will operate properly over the +V
supply voltage range of 3V to 5.5V. The devices are tested and specified for rated accuracy
at their nominal supply voltage. Accuracy will typically degrade 1C/V of variation in +V
S
as it varies from the nominal value.
Note 7:
Limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).
Note 8:
This specification is provided only to indicate how often temperature data is updated. The LM75 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.
Note 9:
For best accuracy, minimize output loading. Higher sink currents can affect sensor accuracy with internal heating. This can cause an error of 0.64C at full
rated sink current and saturation voltage based on junction-to-ambient thermal resistance.
Note 10:
O.S. Delay is user programmable up to 6 “over limit” conversions before O.S. is set to minimize false tripping in noisy environments.
Note 11:
Default values set at power up.
Note 12:
Typicals are at T
A
= 25C and represent most likely parametric norm.
Note 13:
Holding the SDA line low for a time greater than t
TIMEOUT
will cause the LM75B to reset SDA to the IDLE state of the serial bus communication (SDA set
High).
