利顺精密的3轴加速度计DMARD06主要应用于平板电脑和低端智能手机，量程为±2g，7位ADC，封装为LGA 3x3x1mm。与飞思卡尔MMA7660兼容，但价格更便宜，性能更高。

为了符合移动设备低功耗需求，该加速度计拥有低功耗模式和自动唤醒功能。具体功耗情况如下：
Normal模式的功耗：140~300uA@Vop=3V
Low power模式的功耗：15~30uA@Vop=3V
Standby模式的功耗：2uA

DMARD06特征：
* Tri-axial digital accelerometer with ±2g dynamic range
* Embedded 7 bit ADC, I2C digital interface, and temperature sensor for internal compensation
* Low operation voltage of +2.4V ~ +3.6V with minimum interface voltage of +1.7V
* Special low-power operation mode with current consumption below 30uA
* One interrupt pin configurable from two interrupt sources with high-G, freefall, and position change events
* User programmable thresholds and timing for interrupt event configurations
* Built-in high- and low-pass filter with user configurable cutoff frequency
* Auto-Awake function that auto-transit from low-power to normal mode upon interrupt events
* 5000g shock tolerance
* 16-pin LGA package with RoHS compliance and lead-free. Footprint 3mm×3mm, height 1mm.
