Application Notes

  • Accurate Temperature Sensing with an External P-N Junction &mdash AN137
    PDF, 540 Kb, File published: Sep 20, 2012
    Many Linear Technology devices use an external PNP transistor to sense temperature. Common examples are LTC3880, LTC3883 and LTC2974. Accurate temperature sensing depends on proper PNP selection, layout, and device configuration. This application note reviews the theory of temperature sensing and gives practical advice on implementation.
