A1363

A1363 Low Noise, High Precision, Programmable Linear Hall Effect Sensor IC With Advanced Temperature Compensation and High Bandwidth (120 kHz) Analog Output FEATURES AND BENEFITS 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 Continued on the next page… PACKAGE: 4-pin SIP (suffix KT) TN Leadform TF Leadform TG Leadform Not to scale DESCRIPTION The Allegro™ A1363 programmable linear Hall-effect current sensor IC has been designed to achieve high accuracy and resolution without compromising bandwidth. The goal is achieved through new proprietary linearly interpolated temperature compensation technology that is programmed at the Allegro factory and provides sensitivity and offset that are virtually flat across the full operating temperature range. Temperature compensation is done in the digital domain with integrated EEPROM technology, w...
