The A1332 is a 360° contactless high-resolution programmable magnetic angle position sensor. It is designed for digital systems using an I2C interface. This system-on-chip (SoC) architecture includes a front end based on Circular Vertical Hall (CVH) technology, programmable microprocessor-based signal processing, and digital I2C interface. Besides providing full-turn angular measurement, the A1332 also provides scaling for angle measurement applications less than 360°. It includes on-chip EEPROM for flexible programming of calibration parameters. Digital signal processing functions, including temperature compensation and gain/offset trim, as well as advanced output linearization algorithms, provide an extremely accurate and linear output for both ends of shaft applications, as well as off‑axis applications. The A1332 is ideal for automotive applications requiring high speed 360° angle measurements, such as electronic power steering (EPS), transmission, torsion bar, and other systems that require accurate measurement of angles. The A1332 linearization schemes were designed with challenging off-axis applications in mind. This device operates over a wide temperature range of -40 to 125°C.

All I2C Mini Modules are designed to operate at 5VDC. Using a convenient 4-Pin plug, devices can be daisy-chained onto the I2C Bus, eliminating the need for soldering. Simply plug together the devices you need for your next automation application. Pull-up resistors are included with all Dcube Store master devices. If you are wiring in your own I2C port, on-board 4.7K jumper-selectable pull-up resistors are available for convenience purposes. All I2C Mini Modules include an I2C Cable.
