Linear Hall-effect sensor IC
The new A1357 from Allegro MicroSystems Europe is a high-precision,?customer-programmable, linear Hall-effect sensor IC with a ?pulse-width-modulated
current-sourced two-wire output.??Featuring a wide ambient temperature range of -40°C to +150°C, the A1357?device
is targeted at the automotive and industrial sectors, particularly in applications where signals have to travel over relatively long distances in noisy environments. The A1357 converts an analogue signal from its internal hall sensor element to a digitally encoded PWM output signal with a frequency of 1 kHz and a duty cycle that is proportional to an applied magnetic field. The coupled noise immunity of the digitally encoded PWM output is far superior to the noise immunity of an analogue output signal.
