STEVAL-MKI014V1 MEMS 3-axis ±2g/±6g analog-output demonstration board based on the LIS344ALH Data brief Features ■ Normal or power-down mode ■ 2g or 6g full-scale ■ Self-test signals through the use of a jumper ■ RoHS compliant Description The STEVAL-MKI014V1 demonstration board is designed to provide the user with a complete, ready-to-use platform for evaluation of the LIS344ALH. The LIS344ALH is a low power 3axis 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. STEVAL-MKI014V1 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. The kit also provides an easy way to select from the two full scales allowed by the device, and to control its power-down, full-scale, and self-test pins.
