An Energy Efficient Solution by Freescale

Xtrinsic MAG3110 Three-Axis, Digital

Magnetometer

Freescale’s MAG3110 is a small, low-power, digital 3-axis magnetometer.

The device can be used in conjunction with a 3-axis accelerometer to realize an

orientation independent electronic compass that can provide accurate heading

information. It features a standard I

C serial interface output and smart embedded

functions.

The MAG3110 is capable of measuring magnetic fields with an output data rate

(ODR) up to 80 Hz; these output data rates correspond to sample intervals from

12.5 ms to several seconds.

The MAG3110 is available in a plastic DFN package and it is guaranteed to

operate over the extended temperature range of -40°C to +85°C.

Features

• 1.95 V to 3.6 V supply voltage (VDD)

• 1.62 V to VDD IO voltage (VDDIO)

• Ultra small 2 mm x 2 mm x 0.85 mm, 0.4 mm pitch, 10-pin package

• Full-scale range ±1000 T

• Sensitivity of 0.10 T

• Noise down to 0.25 T rms

• Output Data Rates (ODR) up to 80 Hz

• 400 kHz Fast Mode compatible I

C interface

• Low-power, single-shot measurement mode

• RoHS compliant

Applications

• Electronic Compass (e-compass)

• Location-Based Services

Ruggedized Target markets

• Smartphones, personal navigation devices, robotics, UAVs, speed sensing, current sensing and wrist watches with

embedded electronic compasses (e-compass) function.
