Product description

iC-MSB is a sine/cosine sensor signal conditioner with fail-safe 1 Vpp line driver outputs.

The analog PGA front-end takes differential or single-ended signals; current-to-voltage conversion is optional. For ultra-low latency, the signal-path is purely analog from input to output, whereas signal errors are corrected by a digitally-controlled conditioning unit utilizing several D/A converters.
Signal loss detection and level monitoring is included.

Features

  • PGA inputs to 500 kHz for differential and single-ended sensor signals
  • Selectable adaptation to voltage or current signals
  • Flexible pin assignment due to signal path multiplexers
  • Sine/Cosine signal conditioning for offset, amplitude and phase
  • Separate index signal conditioning
  • Short-circuit-proof and reverse polarity tolerant output drivers (1 Vpp to 100 Ω)
  • Stabilized output signal levels due to sensor control
  • Signal and system monitoring with configurable alarm output
  • Supply voltage monitoring with integrated switches for reversed-polarity-safe systems
  • Excessive temperature protection with sensor calibration
  • I2C multimaster interface
  • Supply from 4.3 to 5.5 V, operation within -40 to 125 °C
  • Suitable for SAFETY applications within -25 to 100 °C
  • Verifyable chip release code

Applications

  • Programmable sensor interface for optical and magnetic position sensors
  • Linear gauges and incremental encoders
  • Linear scales
