Note 5:

FS5908 will operate properly over the +Vs supply voltage range from 2.5V to 5.5V. The devices are

tested and specified for rated accuracy at their normal supply voltage, Accuracy will typically degrade 0.15℃/V

of variation in VDD.

Note 6:

Limits are guaranteed to Fortune AOQL (Average Outgoing Quality Level)

Note 7:

This specification is provided only to indicate how often temperature data is updated. The FS5908

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 stopped and restarted after the end of the read.

Note 8:

For best accuracy, minimize output loading. Higher sink currents can affect sensor accuracy with

internal heating. This can cause an error of 0.25℃ at full rated sink current and saturation voltage based on

junction-to-ambient thermal resistance.

Note 9:

ALARM Delay is user programmable up to 8 over limit conversions before O.S. is set to minimize

false tripping in noisy environments.

Note 10:

Typical are at TA=25℃ and represent most likely parametric norm.
