E-Compass

e20CompassThe MXG1300 is a very accurate digital compass from MagnaChip. The compass is used for measuring terrestrial magnetism in the X-, Y- and Z-axis. The compass contains magnetic sensors, a sensor driver circuit, a low noise amplifier, high-resolution ADC and a controller for low-power computation.

In addition to the low-power mode, the MXG1300 supports a normal mode in order to improve the battery life as well. The integrated temperature sensor compensates variations caused by non-linear ADC characteristics across the whole temperature range. Because of the small footprint and low power consumption, the MXG1300 fits perfectly into navigation devices for pedestrians or for intelligent additional facilities (complementary attachments) within the house.

Temperature and Relative Humidity Sensor 

The MXH1100 is a state of the art temperature and relative humidity sensor utilized proven techniques for measuring humidity using polymer dielectric film along with CMOS mixed signal integrated circuits. It provides fully calibrated digital output(I2C, PWM, PDM) and analog output as well. In particular, its analog output allows for easy integration without the
need for additional calibration and externalcomponent.
The resolution can be changed by command (8/12bit up to 12/14bit for RH/T). Every sensor is individually calibrated and tested and the lot identification is printed on the sensor.

 

Key Features: 

  • Function: Humidity / Temperature, Linear / Temp. compensation
  • Response Time: ~10sec
  • Package (mm): 2.8 x 3.6 10- pin DFN
  • Humidity Accuracy: ± 3.0 %
  • VDD: 4.75~5.25V
  • System operating VDD current(5V): 0.3mA @Analog voltage mode
  • Outout: I2C / PWM / PDM / Analog Voltage Selectable by SEL[1:0]
