热销ak8973b 电子指南针芯片

应用在手机，gps上面。我司主要做akm芯片。假一赔百。

1.	si-monolithic 3-axis geomagnetic sensor lsi
2.	measurement range
	-	± 2000t is provieded.
4.	due to the built-in dac for compensating the offset magnetic field generated by such as speakers, the position restraint with parts which generate the offset magnetic field is reduced, and the degree of freedom about layout is expanded.
5.	due to the built-in 8-bit adc and serial interface, x-, y-, and z-axes components of geomagnetism can be output as digital signal.
6.	the serial interface corresponds to the i²c bus.
7.	a dedicated power supply is used for the serial interface, so the low-voltage operation at down to 1.7v is also covered.
8.	a memory for storing the individual adjustment values of sensor sensitivity is built-in. the adjustment values are stored before shipment at akm factory.
9.	the built-in temperature sensor generates the digital a/d-converted data and then the data is output from serial interface as digital data.
10	the major circuit blocks of ak8973n/b/s are activated by the measurement request command from the controller, and transit to the power-down mode automatically at the end of measurement. that characteristic realizes the low power consumption required for mobile phones.
11.	the interrupt function for posting the completion of sensor signal measurement to the external cpu is built-in.
12.	built-in oscillator dispenses with the external clock input.
