A1337 Description
The A1337 is a 0° to 360° angle sensor IC that provides contactless high-resolution angular position data based on magnetic circular vertical Hall (CVH) technology. It has a system-on-chip (SoC) architecture that includes: a CVH front end, digital signal processing, digital SPI, and SENT outputs.
A1337 Key Features
- Contactless 0° to 360° angle sensor IC, for angular position and rotation direction measurement
- Circular vertical Hall (CVH) technology provides a single-channel sensor system, with air gap independence
- 12-bit resolution possible in low-RPM mode, 10-bit resolution in high-RPM mode
- Angle refresh rate (output rate) configurable between 25 and 3200 μs through EEPROM programming
- Capable of sensing magnetic rotational speeds up to 7600 rpm, and up to 30,000 rpm with reduced accuracy
- Serial peripheral interface (SPI; mode 3) and single-edge nibble transmission (SENT) [1]
