The SGM450 is a high-precision linear analog temperature sensor IC, providing an output voltage directly proportional to temperature, making it suitable for various analog temperature measuring and temperature monitoring applications. With a typical accuracy of ±0.5℃ over the 0℃ to +85℃ range, the SGM450 delivers higher accuracy than other pin-compatible devices currently on the market. The SGM450 generates a positive output slope of 10mV per degree Celsius across an extensive temperature ranging from -40℃ to +150℃, powered by a single supply voltage varying from 2.3V to 5.5V.
The SGM450 provides a low quiescent current of 7.5μA (TYP) and a power-on time of 420μs (TYP), making it ideal for battery-powered applications due to its energy-efficient consumption characteristics. The output stage of the SGM450 is structured as a Class-AB type with a maximum output driver capability of 500μA, capable of driving a capacitive load of 1000pF, which is more suitable for connecting with the input stage of analog-to-digital converter (ADC). The SGM450 analog output temperature sensor, with its high accuracy and robust linear output driver, presents a cost-effective solution compared to traditional devices (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℃.
