dm211

功能特点

公司在2012年末推出基于霍尔原理的3轴磁传感器系列产品dm211,产品采用了LGA14(2mm×2mm×0.75mm)的封装,其量程范围为±48Gauss,可广泛应用于各领域。

芯片集成了I²C和SPI接口,用户可以根据需要灵活选择;内部集成16Bits ADC,可达到3mGauss/LSB的高分辨率;一个独立中断输出,及一个可编程为中断输出或外部触发的可编程中断。

工作温度范围为-40℃~+85℃,宽工作电压范围;其待机功耗为3μA

The dm211 is a 3-axis magnetometer targeting low-power applications. The full scale is ±48Gauss. The device is based on the Hall-effect and packaged in a 2.0x2.0x0.75mm land grid array (LGA), it is guaranteed to operate over an extended temperature range from -40°C to +85°C. The output signals(raw X,Y and Z data) will be provided through the I2C fast mode protocol, or via half-duplex SPI. There is an on-board non-volatile memory to store calibration data on-chip.

The dm211 has an on-board temperature sensor which measures the temperature of the dm211 sensor. The temperature can be read out via the communication protocol in a digital format.

The dm211 can operate in three modes: burst mode, single measure mode and wake-up change. The user can change the operating mode an all time through a specific command on the bus. The default start-up mode is single measurement mode(in IDLE state).
