日前,ADI推出一款三轴数字MEMS加速度计ADXL362,据称其功耗为业界最低。它在运动检测唤醒模式下功耗仅为300nA,比同类产品低60%。在全速测量模式下,数据速率为100Hz时,ADXL362的功耗为2μA,比相同频率下的同类产品低80%。“判断一个器件本身的功耗,主要看它的休眠电流是否足够低,是否可控制器件本身的漏电流足够低,”ADI微机械产品线高级应用工程师赵延辉说,“ADXL362的
Recently, ADI introduced a three-axis digital MEMS accelerometer ADXL362, allegedly the lowest power consumption in the industry. It consumes only 300nA in motion-detect wake-up mode, 60% less than competing products. In full-speed measurement mode, the ADXL362 consumes 2μA at a data rate of 100Hz, 80% less than competing products at the same frequency. ”Determine the power consumption of a device itself, depending on whether its sleep current is low enough to control the leakage current of the device itself is low enough, “ said Zhao Yanhui, senior application engineer of the ADI micromechanical product line, ”ADXL362
