If the SPI interface is not used SCK (pin1), MISO (pin3), MOSI (pin4) and CSB (pin7) must be left
floating. Self-test can be activated applying logic “1” (positive supply voltage level) to ST_1 or
ST_2 pins (pins 10 or 9). Self-test must not be activated for both channels at the same time. If ST
feature is not used pins 9 and 10 must be left floating or connected to GND. Inclination signals are
provided from pins OUT_1 and OUT_2.
Typical offset and sensitivity temperature dependencies of the SCA100T are presented in following
diagrams. These results represent the typical performance of SCA100T components. The mean
value and 3 sigma limits (mean ± 3× standard deviation) and specification limits are presented in
following diagrams. The 3 sigma limits represents 99.73% of the SCA100T population.
No.
