CMS300 MEMS Combi-Sensor
The CMS series of MEMS sensors combines a single axis gyro, dual-axis low-g accelerometer, and dedicated control ASIC to deliver angular rate and linear acceleration measurements with class-leading bias and noise over temperature. Enclosed in a hermetically-sealed ceramic LCC surface mount package, the sensors are available in two versions, one that can be mounted flat to a board and an orthogonal version that can be mounted on its side.
The sensors feature user-selectable dynamic range and bandwidth. Sensor measurements, built-in test status and device temperature are all output via a digital SPI interface. Each individual unit is calibrated over the full rated temperature range.
