Note 1: Typical values are defined at TA = 25ºC and VDD = VDDNOM
Note 2: VDDNOM = 5V or 3.3V - the value used at trimming
Note 3: Guaranteed by design and characterization
Note 4 Signal Bandwidth & Signal Phase Shift mentioned here are defined for Z=1 & 2, resp. 500ppm/ºC & 2000ppm/ºC. The option code Z=0has internal filtering
disabled. Products for 0ppm/ºC are targeted for current measurement applications. Therefore, Bandwidth & Phase Shift are not specified. No internal filter enables a
step response time in the order of us. To get an idea of the phase & amplitude behavior over frequency, use a bode diagram for a 1st order RC filter with the
Frequencies specified under “Band width . Also note that Melexis can support you to get an application specific filter setting. Contact your sales contact in such case.
Note 5: Guaranteed by correlation with wafer test and characterization
