Abstract

【課題】　特に、複数の出力モードを簡単に切換可能な磁気検出装置及び前記磁気検出装置を用いた電気製品を提供することを目的としている。 【解決手段】　集積回路２２には２つの出力端子４０，４１と、一対の切換端子５８，５９を備えたモード切換回路５０が設けられている。前記モード切換回路５０では、前記切換端子５８，５９間の短絡状態、あるいは非短絡状態により、前記出力端子４０から、（＋）磁界検出信号、及び（－）磁界検出信号の双方を出力させる１出力モードと、一方の出力端子４０から前記（＋）磁界検出信号を、他方の出力端子４１から前記（－）磁界検出信号を夫々出力させる２出力モードとに切換可能となっている。また前記切換端子５８，５９は装置表面に露出そており、前記短絡状態、および前記非短絡状態は外部から調整可能となっている。
