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. The coupled noise immunity of the digitally encoded PWM is far superior to the noise immunity of an analog output signal.

Features and Benefits

â–ª Two-wire output enables reduced wiring costs in long wire systems
â–ª Simultaneous programming of PWM carrier frequency, quiescent duty cycle (QDC), and sensitivity for system optimization
â–ª Fully differential signal path increases EMC immunity and reduces output offset drifts
â–ª Factory programmed sensitivity temperature coefficient and quiescent duty cycle drift
â–ª Programmability at end-of-line
â–ª Pulse width modulated (PWM) current output provides increased noise and EMC immunity compared to an analog output
â–ª Precise recoverability after temperature cycling â€¢ Duty cycle clamps provide short circuit diagnostic capabilities
â–ª Optional 50% duty cycle calibration test mode at device power up
â–ª Wide ambient temperature range: â€“40Â°C to 150Â°C
â–ª Resistant to mechanical stress
