Temperature Sensors - Thermostats - Solid State

The TMP303GDRLR is a solid-state thermostat designed for a wide range of temperature sensing applications. It provides highly accurate, reliable, and repeatable switching in an extremely small packaging form factor and is designed for operation over a wide temperature range.This makes the TMP303GDRLR ideal for a variety of applications such as: industrial heating systems, medical and lab equipment, consumer electronics, and automotive systems. The TMP303GDRLR is also suitable for outdoor and aviation industries where temperature variability can be severe and reliable accuracy is essential.The tiny, robust design of the TMP303GDRLR provides the convenience of both low-power operation and a sealed ceramic construction making it durable enough to withstand even the most extreme temperature variations. The small form factor also ensures easy, reliable installation in a variety of applications.The inner workings of the TMP303GDRLR are relatively straightforward. At the heart of the device lies a precision temperature-sensitive element whose resistance decreases with a rise in temperature. This is connected to a small form factor printed circuit board containing signal conditioning circuitry which compensates for the resistance of the sensing element and converts it into a voltage signal which can be read by a compatible microcontroller (µC) or other system component.The signal conditioning circuitry is designed to provide a highly linear output over a wide temperature range (up to ±10°C) and can be calibrated to provide an additional accuracy of ±0.25°C. The output of the TMP303GDRLR is an analogue voltage which typically swings between 0-1V depending on the temperature.The device also includes an integrated temperature sensor which can be used either in conjunction with the main sensing element, or separately to provide dual temperature sensing capabilities. The temperature sensor is a silicon-based, chip-type thermistor which provides temperature sensing capabilities with an accuracy of ±0.03°C over a wide range (up to ±25°C).In summary, the TMP303GDRLR is a reliable and highly accurate solid-state thermostat designed for a wide variety of temperature sensing applications. Its small form factor and integrated temperature sensor make it a great choice for applications where space and reliable operation in extreme temperature variations are primary considerations. Moreover, its precision temperature sensing element, combined with smart signal conditioning circuitry ensures accurate, repeatable, and reliable temperature switching.
