A1366

A1366 Low Noise, High Precision, Factory-Programmed Linear Hall-Effect Sensor IC with Advanced Temperature Compensation and High Bandwidth (120 kHz) Analog Output FEATURES AND BENEFITS 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 Continued on the next page… PACKAGE: 4-pin SIP (suffix KT) TN Leadform TF Leadform TG Leadform Not to scale DESCRIPTION The Allegro™ A1366 factory-programmable linear Halleffect current sensor IC has been designed to achieve high accuracy and resolution. The goal is achieved through new proprietary linearly interpolated temperature compensation technology that is programmed at the Allegro factory, which provides sensitivity and offset that are virtually flat across the full operating temperature range. The flat performance over temperature makes ...
