Allegro MicroSystems Inc.

The A1357 from Allegro MicroSystems Inc., Worcester, MA, is a linear Hall effect sensor IC with a PWM current-sourced (2-wire) output and an operating temperature range of –40°C to 150°C. The BiCMOS, monolithic circuit inside the device integrates a Hall element; temperature compensation circuitry; a small-signal, high-gain amplifier; proprietary dynamic offset cancellation circuits; and PWM conversion circuitry. The PWM output duty cycle is proportional to an applied magnetic field. High-frequency offset cancellation clock enables a higher sampling rate. The device is suited for use in automotive and industrial applications.
