Top Features

Packaging

  • Factory programmed sensitivity and quiescent output voltage with high resolution
  • Proprietary segmented linear interpolated temperature compensation (TC) technology provides a typical accuracy of 1% across the full operating temperature range
  • 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
  • Ratiometric sensitivity and quiescent voltage output
  • Precise recoverability after temperature cycling
  • Wide ambient temperature range: –40°C to 150°C
  • Immune to mechanical stress
  • Extremely thin package: 1 mm case thickness
  • AEC Q-100 automotive qualified

The A1366 sensor IC is provided in an extremely thin case (1 mm thick), 4-pin SIP (single in-line package, suffix KT) that is lead (Pb) free, with 100% matte tin lead frame plating.
