Top Features

Packaging

  • Proprietary segmented linear interpolated temperature compensation (TC) technology provides a typical accuracy of 1% across the full operating temperature range
  • Customer programmable, high resolution offset and sensitivity trim
  • Factory programmed sensitivity and quiescent output voltage TC with extremely stable temperature performance
  • High sensitivity Hall element for maximum accuracy
  • Extremely low noise and high resolution achieved via proprietary Hall element and low noise amplifier circuits
  • 120 kHz nominal bandwidth achieved via proprietary packaging and chopper stabilization techniques
  • Patented circuits suppress IC output spiking during fast current step inputs
  • Open circuit detection on ground pin (broken wire)
  • Undervoltage lockout for VCC below specification
  • Selectable sensitivity range between 0.6 and 14 mV/G through use of coarse sensitivity programming bits
  • Ratiometric sensitivity, quiescent voltage output, and clamps for interfacing with application A-to-D converter (ADC)
  • Precise recoverability after temperature cycling
  • Output voltage clamps provide short circuit diagnostic capabilities
  • Wide ambient temperature range: –40°C to 150°C
  • Immune to mechanical stress
  • Extremely thin package: 1 mm case thickness KT package and surface mount TSSOP8 LU package

The A1363 sensor IC is offered in an extremely thin package: 1 mm case thickness KT package and surface mount TSSOP8 LU package that are lead (Pb) free, with 100% matte tin lead frame plating.
