The magnetic angle sensor iC-MA3 is easily configured by pins and runs off a single 3 V to 5.5 V supply. The device outputs conditioned sine/cosine signals representing the axis angle, introduced by a diametric permanent magnet facing the package.
An array of four Hall sensors is used for the differential scanning of the magnetic field, whereas unwanted external stray fields are nearly compensated, and thus not detected. Besides, a high lateral mechanical placement tolerance is obtained easing device installation.
The sine/cosine signals can be output either single-ended or differential, with a pin-configured amplitude controlled to 0.25 V, 0.5 V or 1 V. At full signal bandwidth of 10 kHz, iC-MA3 can track the magnet rotation at up to 60,000 rpm.
