ADXL312ACPZ屬于傳感器變送器的運動傳感器-加速計。由亞德諾半導體技術有限公司制造生產的ADXL312ACPZ運動傳感器 - 加速計加速度計用于檢測并響應運動或振動等加速度的變化。加速度計類型有 X、Y 或 Z 軸上的模擬或數字加速度計，加速度范圍為 ±0.5 g 至 ±2000 g，靈敏度為 1 至 500 k (LSB/g)，輸出類型有模擬電壓、藍牙、數字、DSI、IEPE、I2C、PCM、PWM、射頻和 SPI。

GENERAL DESCRIPTION

The ADXL312 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 SPI (3- or 4-wire) or I2C digital interface.

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, patent pending FIFO technology minimizes host processor load

Built-in motion detection functions for activity/inactivity monitoring

Supply and I/O voltage range: 2.0 V to 3.6 V

SPI (3- and 4-wire) and I2C digital interfaces

Flexible interrupt modes mappable to either interrupt pin

Measurement ranges selectable via serial command

Bandwidth selectable via serial command

Wide temperature range (?40 to +105°C)

10,000 g shock survival

Pb free/RoHS compliant

Small and thin: 5 mm × 5 mm × 1.45 mm LFCSP package

Qualified for automotive applications

APPLICATIONS

Car alarm

Hill start aid (HSA)

Electronic parking brake

Data recorder (black box)
