Analysis of technical highlights‌Qyr嘉泰姆

1. ‌Proportional output design‌Qyr嘉泰姆
   The output voltage is directly associated with the power supply voltage (for example, when the power supply is 5V, the zero output is 2.5V) to avoid signal offset caused by power supply fluctuation and improve system reliability.
2. ‌Industrial anti-interference capability‌Qyr嘉泰姆
   IntegrationHall array Differential samplingAndDynamic temperature compensation, effectively suppress environmental electromagnetic noise and temperature drift, suitable for severe working conditions such as vibration and high temperature.
3. ‌Plug-and-play simplified design‌Qyr嘉泰姆
   The low-noise architecture eliminates external filter circuits, and SOT23-3 packages are compatible with standard patch processes, shortening the development cycle and reducing BOM costs.
