The ISM303DAC is a high-performance, low-power system-in-package featuring a 3D digital linear acceleration sensor and a 3D digital magnetic sensor.
The ISM303DAC has user-selectable linear acceleration full scales of ±2g/±4g/±8g/±16 g and is capable of measuring accelerations with output data rates from 1 Hz to 6400 Hz. The device has a magnetic field dynamic range of up to ±50 gauss with output data rates from10 Hz to 150 Hz. The ISM303DAC includes an I2C serial bus interface that supports standard, fast mode, fast mode plus, and high-speed (100 kHz, 400 kHz, 1 MHz, and 3.4 MHz) and an SPI serial standard interface.
The ISM303DAC has an integrated 256-level first-in, first-out (FIFO) buffer for the accelerometer data which can be used to limit the intervention of the host processor.
The embedded self-test capability allows the user to check the functioning of the sensor in the final application.
The system can be configured to generate an interrupt signal for free-fall, motion detection and magnetic field detection. The magnetic and accelerometer blocks can be enabled or put into power-down mode separately.
The ISM303DAC is available in a plastic land grid array package (LGA) and is guaranteed to operate over an extended temperature range from -40 °C to +85 °C.Key Features
