General Description
The ADXL3121 is a small, thin, low power, 3-axis accelerometer with high resolution (13-bit) measurement up to ±12 g.
Digital output data is formatted as 16-bit twos complement and is accessible through either a serial port interface (SPI) (3- or 4-wire) or I2C digital interface.
Key Features
- Ultralow power: as low as 57 µA in measurement mode and 0.1 µA in standby mode at VS = 3.3 V (typical).
- Power consumption scales automatically with bandwidth.
- User-selectable resolution.
- Fixed 10-bit resolution.
- Full resolution, where resolution increases with g range, up to 13-bit resolution at ±12 g (maintaining 2.9 mg/LSB scale factor in all g ranges).
- Embedded FIFO technology minimizes host processor load.
- Built-in motion detection functions for activity/i.
