9-Axis Magnetometer / Accelerometer / Micro-Amp Magnetic Gyro - KMX61G

The KMX61G is a high-performance, low-power, magnetometer-accelerometer device enhanced with integrated sensor fusion software and auto-calibration algorithms to deliver the industry’s first highly accurate gyro emulation. Optimized for mobile applications, the KMX61G requires only 450µA of power – significantly less than any consumer gyro available today.

Not Recommended for New Designs.


  • Ultra low power: 1 µA typical in standby, 130 µA typical (accelerometer only), 350 µA typical (magnetometer only), and 450µA (operating, both magnetometer and accelerometer)
  • 3x3x0.9mm, 16-pin LGA package
  • 512-byte FIFO buffer with watermarking capability
  • User-selectable ± 2g, 4g, 8g full-sale accelerometer range
  • ±1200µT total magnetometer measurement range
  • Embedded temperature sensor
  • User-selectable ODR from 0.781Hz to 1.6KHz
  • Magnetometer algorithms for auto-calibration and MI rejection
  • Outputs with up to 14-bit resolution
  • Digital (I2C) Output
  • Supply voltages between 1.8 V and 3.3 V
  • Excellent bias stability over temperature. Bias errors resulting from assembly can be trimmed digitally by the user.
  • Embedded features
  • User-configurable motion wake-up and back-to-sleep and wake-up functions
  • Programmable interrupt engine
  • Accelerometer self-test function


  • Emulated gyro output
  • Ultra low power compared to traditional gyro solutions
