tSP

Spike suppression

Pulse width of spikes that must

be suppressed by the input filter

Input filter on SCL and

SDA

Valid for ambient operating temperature: TA = –40 to +125 °C; VDD = 2.25 V to 3.6 V (except where noted).

Typical numbers are for TA = +25 °C; VDD = 3.0 V

Not tested, guaranteed by design.

Accuracy measurements made at resolutions > 10 bits.

SMBus timeout min and max are valid for TA = –30 to +125 °C.
