利顺精密的±4g量程3轴MEMS加速度计DMARD10是DMARD06升级版，主要应用为智能人机接口、游戏和运动检测，适合平板电脑和智能手机，10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：
100Hz ODR时典型功耗为：140uA@3.3V
Standby模式的功耗：8uA

DMARD10特征：
* Tri-axial digital accelerometer with ±4g dynamic range
* 10 bit ADC embedded with I2C digital interface supporting 400kHz high-speed mode
* Flexible sampling rate from below 1 to 100Hz
* Temperature sensor for internal compensation and capable of digital output
* Low operation voltage from +1.8V to +3.6V with interface voltage from +1.8V to +3.3V
* Power consumption for normal mode: 100Hz ODR typical 140uA@3.3V; for standby mode:typical 8uA
* Special low-power mode with current consumption below 60uA
* One interrupt pin as the data-ready signal with selectable polarity and open-drain option
* Build-in low-pass decimation filter with maximum tap number of 32
* 5000g shock tolerance
* 16-pin LGA package with RoHS compliance and lead-free.
* Footprint 3mm×3mm, height 1mm
