The ADXRS401 is a complete, angular rate-sensing gyroscope capable of measuring up to 75 degrees per second. The ADXRS401 uses Analog Devices’ iMEMS® surface micromachining process to create a functionally complete, low cost gyroscope, integrated with all of the required electronics on a single chip.

The ADXRS401 provides designers with a small, low cost gyroscope without compromising performance, quality, or reliability. The ADXRS401’s immunity to shock and vibration greatly improves the performance of navigation systems where environmental conditions could cause inaccurate system outputs.

The manufacturing technique for this device is the same high volume BIMOS iMEMS® process used for high reliability, automotive airbag accelerometers. The output signal, RATEOUT, is a voltage proportional to angular rate about the axis normal to the top surface of the package. A single external resistor can be used to lower the scale factor and increase dynamic range. An external capacitor is used to set the bandwidth.

A precision reference and a temperature output are also provided for compensation techniques. Two digital self-test inputs electromechanically excite the sensor to test proper operation of both sensors and the signal conditioning circuits. The ADXRS401 is available in a 7 mm x 7 mm x 3 mm BGA surface-mount package that significantly improves manufacturability.

The model number is a specific version of a generic that can be purchased or sampled.

Status indicates the current lifecycle of the product. This can be one of 4 stages:

• Pre-Release: The model has not been released to general production, but samples may be available.
• Production: The model is currently being produced, and generally available for purchase and sampling.
• Last Time Buy: The model has been scheduled for obsolescence, but may still be purchased for a limited time.
• Obsolete: The specific part is obsolete and no longer available. Other models listed in the table may still be available (if they have a status that is not obsolete).

The package for this IC (i.e. DIP, SOIC, BGA). An Evaluation Board is a board engineered to show the performance of the model, the part is included on the board.
