SNAS415F – JANUARY 2008 – REVISED MARCH 2013
Electrical Characteristics (continued)
The following specifications apply for VA = +2.7V to +5.5V, GND = 0V, fSCL up to 3.4MHz, fIN = 1kHz for fSCL up to 400kHz,
fIN = 10kHz for fSCL = 3.4MHz unless otherwise noted. Boldface limits apply for TA = TMIN to TMAX: all other limits TA = 25°C
unless otherwise noted.
