Cost-effective sensor eases motion sensing

The ADIS16405 is a complete inertial sensing system that integrates a three-axis gyroscope, magnetometer, and accelerometer that features 0.05° rate-sensor orthogonal-alignment-accuracy and an angular random walk of below 2.0°/√hr and temperature stability of 40 ppm/°C. All its sensors are accessible over a standard SPI interface, which also allows control of internal digital filtering.

The ADIS16300 is a low-cost precision multi-axis inertial sensor that integrates a single-axis gyroscope and a three-axis accelerometer, which are factory calibrated for sensitivity, bias, alignment, and linear acceleration. It features an improved SPI interface to provide faster data collection and configuration control.

Angular rate sensing can be selected for ±75, ±150, and ±300°/sec dynamic range, with ±3g tri-axis acceleration dynamic range. The device offers a 350Hz bandwidth, and up to 1,200-SPS sample rates, with further digital filtering embedded and programmable. A flexible mounting approach enables easier implementation of roll and pitch axis rate sensing.

The ADIS16405 is packaged in a 23mm x 23mm x 23mm module, with samples available now; the ADIS16300 is packaged in a 23mm x 31mm x 7.5mm module and is available in production quantities. Pricing is $412 and $74 each for 1,000-units respectively.
