KTH5702 Series: Low Power, High Accuracy 2D Hall Rotary Position Sensor
The KTH5702 is a highly integrated 2D Hall rotary position sensor designed for low power consumption and high accuracy. It features a highly matched 2D (X-axis, Y-axis) Hall sensor, a multi-level low-power, high-precision zero-drift operational amplifier, and a high-precision 16-bit ADC. The integrated CORDIC algorithm module provides a 16-bit absolute angle position output up to 360. This sensor supports absolute position detection and offers optional SPI or I2C communication interfaces. It is suitable for various applications requiring precise angular measurement, including knobs, smart toys, audio & lighting & home appliances, and instrumentation. The device supports multiple operating modes like Continuous Sensing Mode, Wake-up & Sleep Mode, and Single Conversion Mode, allowing for flexible application in different scenarios.
