The A1330 is a 360° angle sensor IC that provides contactless high-resolution angular position information based on magnetic Circular Vertical Hall (CVH) technology. It has a system-onchip (SoC) architecture that includes: a CVH front end, digital signal processing, and an analog output driver. It also includes on-chip EEPROM technology, capable of supporting up to 100 read/write cycles, for flexible end-of-line programming of calibration parameters. Broken ground wire detection and user-selectable output voltage clamps make the A1330 ideal for high-reliability applications requiring high-speed 0° to 360° angle measurements.
The A1330 provides adjustable internal averaging, allowing response time to be traded for resolution. This is ideal for applications operating at low rotational velocities requiring high precision. For higher RPM applications, the A1330 provides industry-leading analog response time when no averaging is enabled.
With programmable angle scaling, the A1330 supports applications requiring short angular displacements, while maintaining full dynamic range on the output. Programmable minimum and maximum angle thresholds allow diagnosis of mechanical failures.
The A1330 is available as either a single or dual die option, in an 8-pin TSSOP. The package is lead (Pb) free with 100% matte-tin leadframe plating.
