LIS3DHH MEMS motion sensor: three-axis digital output accelerometer Datasheet - production data Applications Precision inclinometer Platform and antenna stabilization Leveling instruments Ceramic cavity LGA-16 Description (5x5x1.7 mm) The LIS3DHH is an ultra-high-resolution and low- noise three-axis linear accelerometer. The LIS3DHH has a full scale of 2.5 g and is Features capable of providing the measured accelerations to the application through an SPI 4-wire digital 3-axis, 2.5 g full-scale interface. Ultra-low noise performance: 45 g/Hz The sensing element is manufactured using a Excellent stability over temperature dedicated micromachining process developed by (<0.4 mg/C) and time STMicroelectronics to produce inertial sensors 16-bit data output and actuators on silicon wafers. SPI 4-wire digital output interface The IC interface is manufactured using a CMOS Embedded temperature sensor process that allows a high level of integration to design a dedicated circuit which is trimmed to 12-bit temperature data output better match the characteristics of the sensing Embedded FIFO (depth 32 levels) element. High shock survivability The LIS3DHH is available in a high-performance Extended operating temperature range (low-stress) ceramic cavity land grid array (CC (-40 C to +85 C) LGA) package and can operate within a temperature range of -40 C to +85 C.
