SAR100 Angular Rate Sensor

Description

Calibrated and compensated digital gyro sensor with SPI interface housed in a rigid custom ceramic LCC package to accommodate for either horizontal or vertical mounting.

Application areas

  • Industrial
  • Agriculture
  • Aerospace
  • Subsea
  • Rescue
  • Maritime

Key features

  • Horizontal and vertical mounting
  • High reliability and robustness over long lifetime
  • Low vibration sensitivity
  • High overload and shock capability
  • Butterfly balanced design for high mechanical common mode rejection
  • Closed-loop force feedback operation with electrostatic frequency tuning
  • Low bias drift
  • Ideal mono crystalline Si material
  • Wafer level sealing with controlled Q-factor
  • Low power
  • Single voltage supply
  • Fully digital with SPI communication and on chip OTP calibration
  • Digitally controlled sample rate
  • Bandwidth defined by built in 4th order digital LP filter
  • Intrinsic continuous diagnostic monitoring
  • Temperature sensor
  • No external components required

Performance

SAR100 is offered in different ranges, has DC response, with low bias drift and noise, and incorporates a temperature sensor. A SPI interface enables easy and effective communication between customer application and sensor. A number of functions are available through the digital SPI interface including advanced self diagnostics.
