A1357 Datasheet PDF (Two-Wire High Precision Linear Hall-Effect Sensor)

A1357 - Two-Wire High Precision Linear Hall-Effect Sensor

Description

The A1357 device is a high precision, programmable two-wire Hall-effect linear sensor IC with a pulse width modulated (PWM) current.

The A1357 device converts an analog signal from its internal Hall sensor element to a digitally encoded PWM signal.

Features

Two-wire output enables reduced wiring costs in long wire systems.
Simultaneous programming of PWM carrier frequency, quiescent duty cycle (QDC), and sensitivity for system optimization.
Fully differential signal path increases EMC immunity and reduces output offset drifts.
Factory-programmed sensitivity temperature coefficient and quiescent duty cycle drift.
Programmability at end-of-line.
Pulse width modulated (PWM) current output provides increased noise and EMC.
