A33003 Description

The A33003 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-on-chip (SoC) architecture that includes: a CVH front end, digital signal processing to calculate the angular position data, and selectable output protocols (SPI, SENT, or PWM).

A33003 Applications

  • Programmable via Manchester encoding on the output line to reduce external wiring and enable in-application programming when in PWM or SENT mode
