GMA303 ±16g Tri-Axial Digital Accelerometer


General Introduction
GMA 303 is a tri-axial digital accelerometer with ±16g dynamic range and 13-bit ADC resolution.
It integrates MEMS sensing element and a CMOS conditioning IC in a compact 2×2×1 mm3
package. The high resolution makes feasible precise applications like e-Compass tilt
compensation. The wide sensing range further opens enough windows for motion detection.
Finally the small form factor makes it an easy fit-in for compact applications like wearable.
Features
 Tri-axial digital accelerometer with ±16g dynamic range
 13 bit ADC resolution with sensitivity 256 LSB/g
 Digital I2C interface supporting both fast mode (400kHz) and normal mode (100kHz)
 Temperature sensor for internal compensation and capable of digital output
 Operation voltage: +2.4V ~ +3.6V; IO interface voltage: +1.8V ~ +3.6V
 Power consumption:
 Continuous mode (CM): typical 140uA to 250uA for 128Hz ODR
 Non-Continuous mode (NCM): typical 85uA to 100uA for 1~8Hz ODR
 Suspend current < 1uA
 One interrupt pin with selectable polarity and push-pull/open-drain option
 Built-in functions:
 Data-ready interrupt
 Motion detection: normal and differential modes
 Auto-Wake/Sleep transition
 4-tap moving average filter with high-/low-pass option
 5000g shock tolerance
 12-pin QFN lead-free package. Footprint: 2mm × 2mm, height: 1mm.
 RoHS compliance
