The AIS328DQ is an ultra low-power high performance 3-axis linear accelerometer with a digital serial interface SPI standard output.
The AIS328DQ is an ultra low-power, high-performance 3-axis linear accelerometer featuring a digital serial interface compatible with both SPI and I2C standards. It is designed for automotive applications such as telematics, in-dash navigation, and tilt measurement. The device offers dynamic user-selectable full-scales of ±2g, ±4g, and ±8g, with an output data rate ranging from 0.5 Hz to 1 kHz. It includes features like embedded self-test, programmable interrupt generators, and a system sleep/wakeup function to optimize power consumption, which can be as low as 10 µA in ultra low-power mode. The sensor operates over an extended temperature range of -40 °C to +105 °C and is available in a small 4x4 mm QFPN package.
