High-resolution programmable angle sensor with SPI interface

Available now from Digi-Key stock, Allegro's A1334 is a 360 degree contactless, high resolution magnetic angle position sensor based on circular vertical hall (CVH) technology. The sensor is a system-on-a-chip device that includes a CVH front end, programmable digital signal processing and SPI interface. The A1334 is seen as ideal for automotive and industrial applications requiring end-of-shaft, high-speed, 0 to 360 degree angle measurements. With a fast angle refresh rate of 25µsecs it produces accurate angle measurements even on target magnets rotating at very high RPM rates. It is also ideal for slower speed applications where it can provide accurate angle measurements with 12-bits of resolution, says the company.
