KTH7812 16-bit High-Precision Low-Latency Hall Magnetic Encoder

The KTH7812 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 on-axis and off-axis scenarios. Capable of accurately outputting angle information at speeds ranging from 0 to 120,000 rpm, the KTH7812 is suitable for applications requiring precise angle measurement and speed control. It supports programmable ABZ orthogonal pulse output (4-4096 steps/revolution) and programmable 1-8 pole pair UVW incremental output. The sensor also features a four-wire SPI output for communication and data exchange, integrated magnetic field strength detection with programmable thresholds for monitoring, and an MTP (Multi-Time Programmable) memory for storing configuration parameters like zero angle position, ABZ encoder settings, and magnetic field detection thresholds.
