A1330
Description
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.
Key Features
- Contactless 0° to 360° angle sensor IC, for angular position, rotational speed, and direction measurement
- Single and dual die options available in same package
- Non-volatile memory (EEPROM) for use in application trimming/calibration
- Circular Vertical Hall (CVH) technology provides a single-channel sensor system with air gap independence
- Angle Refresh Rate (output rate) configurable between 25 and 3200 µs through EEPROM programming
- Customer-programmable output clamp levels provide short-circuit diagnostic capabilities
- Open-circuit detection on ground pin (broken wire)
- Undervoltage lockout for VCC below specification
- Fine angle scaling for short-stroke applications
- Missing Magnet Error flag for notifying controller of low magnetic field level
