The device features user-selectable full-scale ranges of +\/-2g and +\/-6g, with sensitivity of 660 mV\/g (typical at +\/-2g, 3.0V supply) and zero-g offset of 1.5V. The output voltage is ratiometric to the supply voltage, simplifying ADC interface design. Factory trimming ensures consistent sensitivity and offset across devices. The device operates from 2.4V to 3.6V with current consumption of 650 uA typical. An integrated self-test function allows system integrity verification by applying an electrostatic force to the sensing element. The MEMS sensing element can survive mechanical shocks up to 10,000g.","working_principle":"The LIS344ALHTR uses a capacitive MEMS sensing element with a proof mass suspended by silicon springs. (1) Sensing Element: Each axis consists of a movable proof mass with interdigitated fingers forming differential capacitors with fixed electrodes. When acceleration is applied along any axis, the proof mass displaces, changing the differential capacitance. (2) Capacitance-to-Voltage: An internal C-V converter measures the capacitance change and produces a voltage proportional to the applied acceleration. The analog output voltage is ratiometric to the supply voltage (VDD\/2 at zero-g). (3) Range Selection: The FS pin selects between +\/-2g (FS=0) and +\/-6g (FS=1) full-scale ranges by adjusting the capacitive sensitivity. (4) Bandwidth: The output bandwidth is set by external capacitors on the Cx, Cy, Cz pins, allowing cutoff frequency from 40 Hz to 1500 Hz. (5) Self-Test: Setting the ST pin activates an electrostatic force on the proof mass, producing a known output deflection that verifies sensor functionality.","pin_description":"
