ADXL362傳感器變送器的運(yùn)動(dòng)傳感器-加速計(jì)規(guī)格書PDF中文資料

ADXL362屬于傳感器變送器的運(yùn)動(dòng)傳感器-加速計(jì)。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的ADXL362運(yùn)動(dòng)傳感器 - 加速計(jì)加速度計(jì)用于檢測并響應(yīng)運(yùn)動(dòng)或振動(dòng)等加速度的變化。加速度計(jì)類型有 X、Y 或 Z 軸上的模擬或數(shù)字加速度計(jì)，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(lán)牙、數(shù)字、DSI、IEPE、I2C、PCM、PWM、射頻和 SPI。

GENERAL DESCRIPTION

The ADXL362 is an ultralow power, 3-axis MEMS accelerometer that consumes less than 2 μA at a 100 Hz output data rate and 270 nA when in motion triggered wake-up mode. Unlike accelerometers that use power duty cycling to achieve low power consumption, the ADXL362 does not alias input signals by undersampling; it samples the full bandwidth of the sensor at all data rates.

FEATURES

Ultralow power

Power can be derived from coin cell battery

1.8 μA at 100 Hz ODR, 2.0 V supply

3.0 μA at 400 Hz ODR, 2.0 V supply

270 nA motion activated wake-up mode

10 nA standby current

High resolution: 1 mg/LSB

Built-in features for system-level power savings:

Adjustable threshold sleep/wake modes for motion activation

Autonomous interrupt processing, without need for microcontroller intervention, to allow the rest of the system to be turned off completely

Deep embedded FIFO minimizes host processor load

Awake state output enables implementation of standalone, motion activated switch

Low noise down to 175 μg/√Hz

Wide supply and I/O voltage ranges: 1.6 V to 3.5 V Operates off 1.8 V to 3.3 V rails

Acceleration sample synchronization via external trigger

On-chip temperature sensor

SPI digital interface

Measurement ranges selectable via SPI command

Small and thin 3 mm × 3.25 mm × 1.06 mm package
