上电后LIS2DM的电流消耗约为100uA?
连接是:
Pin1:外部4K7至3V的SCL
Pin2:外部4K7至3V的SDA
Pin3:SA0连接到GND
Pin4:/ CS连接到3V
Pin5:INT2打开
Pin6:INT1到输入端口uP
Pin7,8:3V
Pin9-14:GND
可能是Pin3上有一个内部上拉,我应该将SA0线连接到3V以获得低功耗?

after power up the LIS2DM the current consump
tion is about 100uA ?!
The connection is:
Pin1 : SCL with a external 4K7 to 3V
Pin2 : SDA with a external 4K7 to 3V
Pin3 : SA0 connected to GND
Pin4 : /CS connected to 3V
Pin5: INT2 open
Pin6: INT1 to Input Port uP
Pin7,8: 3V
Pin9-14: GND
Could it be that there is an internal pull-up on Pin3 and I should connect the SA0 line to 3V to get a low power consumption ?
