... Top Range Wh Product Weight Note: 1 The product is factory calibrated at 5.0V. The device can be powered from 4.5V to 5.5V. Voff, So and Vt parameters will vary with supply voltage. 2 Typical specifications are not guaranteed 3 Verified by wafer level test and measurement of initial offset and sensitivity 4 Zero-g level and sensitivity are essentially ratiometric to supply voltage ...

... Sensitivity Tolerance describes the range of Sensitivities of a large population of sensors. Zero-g level describes the actual output signal if there is no acceleration present. A sensor in a steady state on an horizontal surface will measure axis and axis whereas the Z axis will measure +1g. The output is ideally for a 5.0V powered sensor Vdd/2 = 2500mV. A deviation from ideal 0-g level (2500mV in this case) is called Zero-g offset ...

... Self Test allows to test the mechanical and electric part of the sensor, allowing the seismic mass to be moved by means of an electrostatic test-force. The Self Test function is off when the ST pin is connected to GND. When the ST pin is tied at Vdd an actuation force is applied to the sensor, simulating a definite input acceleration. In this case the sensor outputs will exhibit a voltage change in their DC levels which is related to the selected full scale and depending on the Supply Voltage through the device sensitivity ...

... Factory calibration The IC interface is factory calibrated for Sensitivity (So) and Zero-g Level (Voff). The trimming values are stored inside the device by a non volatile structure. Any time the device is turned on, the trimming parameters are downloaded into the registers to be employed during the normal operation ...

... Power supply decoupling capacitors (100nF ceramic or polyester + 10µF Aluminum) should be placed as near as possible to the device (common design practice). The LIS3L02AS5 allows to band limit Voutx, Vouty and Voutz through the use of external capacitors. The re-commended frequency range spans from 1.5 KHz. In particular, capacitors must be added at output pins to implement low-pass filtering for antialiasing and noise reduction ...
