IXZ-2150 Integrated Dual Axis Digital-Output Gyroscope

Overview

InvenSense Triple Axis Digital Output Gyroscope

The IXZ-2150 is a single-chip, digital-output, 2-axis MEMS gyro IC with programmable full-scale ranges of ±250, ±500, ±1000, and ±2000 degrees/sec (dps), which is useful for precision tracking of both fast and slow motions. Factory-calibrated initial sensitivity reduces production-line calibration requirements. The part’s on-chip FIFO simplifies system timing and lower system power consumption. The FIFO allows a system microcontroller to burst read the sensor data and then go to sleep while the IXZ-2150 collects more data.

Other industry-leading features include on-chip 16-bit ADCs, programmable digital filters, a precision clock with 1% variation from -40°C to 85°C, an embedded temperature sensor, and programmable interrupts. Parts are available with a Fast-Mode I²C serial interface, a VDD operating range of 2.1 to 3.6V, and a VLOGIC interface voltage from 1.71V to 3.6V.

By leveraging its patented and volume-proven Nasiri-Fabrication platform, which integrates MEMS wafers with companion CMOS electronics through wafer-level bonding, InvenSense has driven the IXZ-2150 package size down to a footprint of 4x4x0.9mm (QFN), while providing the highest performance, lowest noise, and the lowest cost semiconductor packaging to address a wide range of handheld consumer electronic devices. The device provides the highest robustness by supporting 10,000g shock in operation. The highest cross-axis isolation is achieved by design from its single silicon integration.
