3 axes Ultra Low Power Accelerometer - LIS3DH
AIS328DQ is new automotive-qualified low-g accelerometer offers excellent stability
The AIS328DQ is an ultra low-power high performance three axis linear accelerometer with a digital serial interface SPI standard output.
An I2C compatible interface is also available.
The device features ultra low-power operational modes that allow advanced power saving and smart sleep-to-wakeup functions. The AIS328DQ has dynamic user-selectable full-scales of ±2g/±4g/±8g and it is capable of measuring accelerations with output data rates from 0.5 Hz to 1 kHz.
The self-test capability allows the user to check the functioning of the sensor in the final application.
The device may be configured to generate an interrupt signal through inertial wakeup/free-fall events, or by the position of the device itself.
Thresholds and timing of interrupt generators are programmable by the end user on-the-fly. Available in small Quad Flat Pack no-lead package (QFPN) with a 4x4 mm footprint, the AIS328DQ is able to respond to the trend towards application miniaturization, and is guaranteed to operate over a temperature range from -40 °C to +105 °C.
