Product Overview
ADXL312 is a small, thin, low power, 3-axis accelerometer with high resolution (13bit) measurement up to ±12g. Digital output data is formatted as 16bit twos complement and is accessible through either a serial port interface (SPI) (3- or 4-wire) or I²C digital interface. It is well suited for car alarm or black box applications. It measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. Its high resolution (2.9mg/LSB) enables resolution of inclination changes of as little as 0.25°. A built-in FIFO facilitates using oversampling techniques to improve resolution to as little as 0.05° of inclination. Several special sensing functions are provided. Activity and inactivity sensing detects the presence or absence of motion and whether the acceleration on any axis exceeds a user-set level. Typical applications are car alarm, hill start aid (HSA), electronic parking brake, data recorder (black box).
- Power consumption scales automatically with bandwidth
- Embedded FIFO technology minimizes host processor load
- Built-in motion detection functions for activity/inactivity monitoring
- Flexible interrupt modes mappable to either interrupt pin
- Measurement ranges selectable via serial command, bandwidth selectable via serial command
- Operating voltage range from 2 to 3.6V (TA=-40°C to +105°C, VS=VDD I/O=3.3V, acceleration=0g)
- Supply current is 170µA typ (data rate
100Hz, TA=-40°C to 105°C, VS=VDD I/O=3.3V, acceleration=0g) - Turn-on (wake-up) time is 1.4ms (TA=-40°C to +105°C, VS=VDD I/O=3.3V, acceleration=0g)
- 32-lead LFCSP package
- Temperature rating range from -40°C to +105°C
