(1) Excludes effect of external magnetic fields. See the  Accuracy Parameters section for details to calculate error due to external magnetic fields.
(3) RTI = referred-to-input. Output voltage is divided by device sensitivity to refer signal to input current. See the  Parameter Measurement Information  section.
(4) Thermally limited by junction temperature. Applies when device mounted on TMCS1100EVM . For more details, see the Safe Operating Area section.
(5) Lifetime and environmental drift specifications based on three lot AEC-Q100 qualification stress test results. Typical values are population mean+1σ from worst case stress test condition. Min/max are tested device population mean±6σ; devices tested in AEC-Q100 qualification stayed within min/max limits for all stress conditions. See  Lifetime and Environmental Stability section for more details.
(6) Refer to the  Transient Response section for details of frequency and transient response of the device.
(7) Centered parameter based on  TMCS1100EVM PCB layout. See  Layout section. Device must be operated below maximum junction temperature.
