3-axis electronic compass for portable appliances

Tokyo Japan, Oct 30 2013, Asahi Kasei Microdevices Corporation (AKM) had launched the AK09912,its lastest 3-axis

electronis compass for portable appliance, and sample shipments are under way. 

 

AK09912C featuring lower driving voltage and lower current consumption in a package that offers footprint compatibility with the AK8963C.

 

Distinguishing features of the AK09912C are as follows:

 

(1) Silicon monolithic Hall-effect magnetic sensor with magnetic concentrator realizes 3-axis magnetometer on a silicon chip.

     Analog circuit, digital logic, power block and interface block are also integrated on a chip.

(2) Wide dynamic measurement range and high resolution with lower current consumption.

      Output data resolution: 16-bit (0.15 μT/LSB)

      Measurement range: ± 4900 μT

      Average current at 100Hz repetition rate: 1mA (typ.)

(3) Operating supply voltage:

     Analog power supply +1.7V to +3.6V

     Digital Interface supply +1.65V to analog power supply voltage.

(4) Device is worked by on-chip oscillator so no external clock source is necessary.

(5) Self test function with internal magnetic source to confirm magnetic sensor operation on end products.    

(6) Built-in Noise Suppression Filter (NSF) keeps magnetic sensor output stable.

(7) Built-in temperature sensor to monitor the temperature while operation.
