AS5048A-HTSP

Overview

The AS5048A-HTSP is a 14-bit contactless magnetic rotary position sensor designed for high-resolution 360-degree angle measurement. It utilizes Hall-effect technology to provide accurate positioning data via a standard SPI interface, eliminating the mechanical wear associated with traditional potentiometers. The device features integrated linearization and internal automatic gain control to maintain accuracy across varying magnetic field strengths.

Why Choose This Part

The sensor offers a high 14-bit resolution (0.0219 degrees per LSB) and includes a zero-position programming feature for easy mechanical alignment during assembly. Its tolerance for magnet misalignment and air gap variations simplifies the mechanical design process compared to optical encoders. The SPI interface allows for simple integration with most microcontrollers while providing diagnostic bits for magnetic field strength monitoring.

Applications

Getting Started

To evaluate the sensor, use the AS5048-DB adapter board which breaks out the SPI pins for connection to a microcontroller. Ensure a diametrically magnetized magnet is positioned within 0.5mm to 3mm of the chip surface for optimal signal integrity. Developers can use standard SPI libraries to read the 14-bit angle register and monitor the error flags for out-of-range magnetic conditions.
