BMX160

General Description

The BMX160 is a 9-axis sensor consisting of a state-of-the-art 3-axis, low-g accelerometer, a low power 3-axis gyroscope and a 3-axis geomagnetic sensor. It has been designed for low power, high precision 9-axis applications in mobile phones, tablets, wearable devices, remote controls, game controllers, head-mounted devices and toys. Due to the small form factor of the compact 14-pin 2.5 × 3.0 × 0.95 mm3 LGA package, BMX160 can be ideally integrated into wearables like smart watches or glasses for augmented reality. When accelerometer and gyroscope are in full operation mode and the geomagnetic sensor in normal mode, power consumption is typically 1465 µA, enabling always-on applications in battery driven devices. The BMX160 offers a wide VDD voltage range from 1.71 V to 3.6 V and a VDDIO range from 1.2 V to 3.6 V, allowing the BMX160 to be powered at 1.8 V for both VDD and VDDIO.
