LSM303DLH chip accelerometer and magnetometer, A/D converter and signal coherent circuit integration in together, still through the I2C bus and communication processor.Using a single chip to realize the six axis and output of data detection, reduces the customer's design difficulty, reduced the PCB footprint area, decrease the cost of the device
LSM303DLH requires very little peripheral devices, the connection is also very simple, magnetometer and accelerometer and processors have their own a I2C bus communication.If the customer's I/O interface level of 1.8V, Vdd_dig_M, Vdd_IO_A and Vdd_I2C_Bus are 1.8 V power supply, Vdd use above 2.5 V power supply;If the customer interface level of 2.6V, besides Vdd_dig_M requirements 1.8 V, the other can use a 2.6 V.In the mentioned above, LSM303DLH setting/reset circuit are needed to maintain AMR main magnetic field.C1 and C2 for setting/reset circuit external matching capacitance, setting due to pulse and reset pulse has certain requirements, recommend that users don't modify the size of C1 and C2
Needed to realize the function of electronic compass, a three-axis magnetic sensor detection magnetic field and a three-axis accelerometer.As the micro mechanical technology mature, stmicroelectronics will launch three axis magnetometer and three-axis accelerometer integrated in a wrapper LSM303DLH combined sensor module, convenience of customers in a short period of time to design low cost, high performance electronic compass
