Description
The LSM6DSO32 is a system-in-package featuring a 3D digital accelerometer and 3D digital gyroscope boosting power performance to 0.55 mA in high-performance mode and enabling always-on low-power features for an optimal motion experience for the consumer.
The LSM6DSO32 supports main OS requirements, offering real, virtual and batch sensors with 9 kbytes for dynamic data batching. ST's family of MEMS sensor modules leverages the robust and mature manufacturing processes already used for the production of micromachined accelerometers and gyroscopes. The various sensing elements are manufactured using specialized micromachining processes, while the IC interfaces are developed using CMOS technology that allows the design of a dedicated circuit which is trimmed to better match the characteristics of the sensing element.
The LSM6DSO32 has a full-scale acceleration range of $\pm 4/\pm 8/\pm 16\pm 32$ g and an angular rate range of $\pm 125/\pm 250/\pm 500/\pm 1000/\pm 2000$ dps.
High robustness to mechanical shock makes the LSM6DSO32 the preferred choice of system designers for the creation and manufacturing of reliable products. The LSM6DSO32 is available in a plastic land grid array (LGA) package.
