AF9838 / AF6838D

       

• Gain market share in drone, robotics, and industrial applications by providing a magnetic sensor with 3.3V VDD and high output data rate.

• The AF9838 QFN/ AF6838D WLCSP is a high-performance, low-noise  3-axis magnetic sensor operating at 3.3 V.

• The Quad Flat No-Lead (QFN) package supports moisture sensitivity levels up to MSL1, ensuring high-reliability assembly and suitability for harsh environmental conditions. Designed for high-precision magnetic field sensing, the AF9838 features ultra-low noise, excellent linearity, and stable output across a wide temperature range. It is especially well-suited for applications such as drones, industrial robots, and AIoT. The sensor performs reliably under dynamic, static, and transitional motion states, enabling accurate orientation and motion tracking. An integrated fast calibration algorithm further simplifies system integration and enhances overall reliability and user experience.
