公司在2012年末推出基于霍爾原理的3軸磁傳感器系列產品dm211，產品采用了LGA14（2mm×2mm×0.75mm）的封裝，其量程范圍為±48Gauss，可廣泛應用于各領域。

芯片集成了I²C和SPI接口，用戶可以根據需要靈活選擇；內部集成16Bits ADC，可達到3mGauss/LSB的高分辨率；一個獨立中斷輸出，及一個可編程為中斷輸出或外部觸發的可編程中斷。

工作溫度范圍為-40℃～+85℃，寬工作電壓范圍；其待機功耗為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).
