The SGM450 is a precision integrated-circuit linear analog temperature sensor with an output voltage proportional to temperature, which can be used in multiple analog temperature-sensing or temperature compensation applications. Featuring typical accuracy of ±0.5℃ from 0℃ to +85℃ temperature range, the SGM450 is more accurate than similar pin-compatible devices on the market. The SGM450 provides a positive slope output of 10mV/℃ over a wide temperature range of -40℃ to +150℃ and it operates from a single 2.3V to 5.5V power supply.
The SGM450 features a low 7.5μA typical quiescent current and a 420μs typical power-on time, and this low power consumption feature enables SGM450 suitable for battery-powered applications. A Class-AB structure output driver provides a strong 500μA maximum output current capability for driving heavy load up to 1000pF, making it well suited to source the input of a sample-and-hold analog-to-digital converter (ADC). With excellent accuracy and a strong linear output driver, the SGM450 analog output temperature sensor is a cost-effective alternative to passive thermistors.
The SGM450 is available in Green SC70-5 and SOT-23 packages. It is specified over the extended industrial temperature range from -40℃ to +150℃.
