KTH5772 - Gaming Joystick 3D Hall Sensor
KTH5772
Gaming Controller Joystick Optimized 3D Hall Position Sensor
Product Overview
KTH5772 is a 3D Hall magnetic sensor specifically designed for joystick applications in gaming controllers. It features advanced algorithms optimized for linearity, response rate, and sensitivity requirements in gaming peripherals.
Based on 3D Hall technology, KTH5772 integrates X, Y, and Z axis Hall elements to sense the magnetic flux density vector components (BX, BY, BZ) from a moving magnet. The signal chain uses high-precision amplifiers with a 16-bit ADC, feeding a high-performance DSP for data processing.
