HQ Series

・Which is better when driving HQ series hall elements, the constant current drive or constant voltage drive?
・The temperature coefficient of the hall element output voltage is approx. -0.2% per °C for the constant voltage drive, and approx. -0.4% per °C for the constant current drive. As you see, the constant voltage drive has better coefficient, therefore basically use in the constant voltage drive.
