The KTH7814 is a high-precision absolute angle Hall sensor chip offering up to 16-bit resolution for absolute angle output. It enables non-contact magnetic field angle measurement in both axial and off-axis scenarios. Capable of rapid and accurate angle information output across a speed range of 0-120,000rpm, it is suitable for applications requiring precise angle measurement and speed control. The KTH7814 provides flexible angle output modes, including programmable ABZ quadrature pulse output (up to 4096 steps/revolution) and 4-wire SPI output for communication. It features integrated magnetic field strength detection with programmable thresholds for monitoring and alarm functions, and an MTP (Multi-Time Programmable memory) for storing configuration parameters like zero angle position, ABZ settings, and magnetic field detection thresholds.
