The LM57 is a precision ±0.7°C temperature sensor with resistor-programmable temperature switch. This device has dual output and the trip temperature (TTRIP) is programmable by using two external 1% ...

Before you start building a digital temperature sensing circuit, you must take the pure mechanical aspects (not treated in this article) and the electro-thermal aspects of your design into account. To ...

Temperature is generally known as the most sensed physical attribute in the sensor world. A wide range of temperature sensors have been developed over the years, including negative temperature ...

Most electronic engineers know that a transistor’s base-emitter voltage (V BE) has a temperature coefficient (TC) of about -2 mV/°C. However, for precision temperature sensors, “about” isn’t good ...
