STEVAL-MKI019V1

STEVAL-MKI019V1 Demonstration kit for the LIS302SG Data brief Features ■ Normal mode or power-down mode ■ Multiplexed output ■ Self-test signals through the use of a jumper ■ RoHS compliant ) s ( ct u d o Description The STEVAL-MKI019V1 demonstration board is designed to provide the user with a complete, ready-to-use platform for the evaluation of the LIS302SG. The LIS302SG is a low-power 3-axis linear capacitive accelerometer that includes a sensing element and an IC interface capable of taking information from the sensing element and providing an analog signal to an external application. ) (s r P e s b O t e l o STEVAL-MKI019V1 In addition to the MEMS sensor, the system includes a linear voltage regulator and a rail-to-rail low noise quad amplifier configured as a noninverting buffer, making both direct sensor outputs and buffered sensor outputs available to the user. t c u d o r P e The STEVAL-MKI019V1 also provides an easy way to control the power-down and self-test pins. t e l o s b O December 2010 Doc ID 18298 Rev 1 For further information contact your local STMicroelectronics sales office. 1/4 www.st.com 4 2/4 Doc ID 18298 Rev 1 * 2 + 2 + 2 + 0$ 34 3 3 6OUT 9Q 6OUT8Q 6OUT9 6OUT: '.$ 6OUT?MUX !UX?IN 6DD 6OU T8 #X N& 69 Q #Y N& 6OUT:Q 6OUT9Q  !UX?)N 6OUT?-UX 6OUT?-UX"UFF      5 -OTION3ENSOR 6$$ 68Q *           6OUT?-UX 6OUT?-UX"UFF 43 6/54 6/54 6  6  6 6 6## '.$ 6 6 6  6  6/54 6/54 5 u d o #Z N& r P e     2SVD 2SVD 2SVD       d o r * # N& 0OWER?3UPPLY t c u ) (s * * # U& 6$$ # N&   * t e l o s b O             P e 2 + ,%     5    *  6OUT?-UX"UFF  6OUT?-UX   6OUT :Q    6: Q 6OUT8Q 6OUT9Q 6OUT:Q    * 3ENSOR/UTPUT "UFFERED/UTPUT Schematic diagram 6$$     t e l o 032 # U& 6$$ s b O   * 68Q 69Q 6:Q Figure 1.
