Angular Hall Sensor with Sin/Cos Output, Cascadable

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. The sine/cosine signals can be output either single-ended or differential, with a pin-configured amplitude controlled to 0.25V, 0.5V or 1V. Multiple iC-MA3 devices can be cascaded to sense several rotary axes, one at a time, but sharing a common analog signal bus.
