SAR10 / SAR10H

Description

Calibrated and compensated digital angular rate sensor with SPI interface in a robust miniaturized surface mountable SOIC-package. Included high-pass filter blocks the bias (zero-point) signal and makes the device non-sensitive for bias drift effects.

Application areas

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

Key features

  • High reliability and robustness over long lifetime
  • Low vibration sensitivity
  • High overload and shock
  • Butterfly balanced design for high mechanical common mode rejection
  • Closed-loop force feedback operation with electrostatic frequency tuning
  • 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
  • No external components required

Performance

Two models of this product are available depending on demands in target application. The lower range model has a lower scale factor (higher resolution) and better performance in regards to noise. 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.
