LM94021BIMG (TEXAS INSTRUMENTS)

The LM94021BIMG is a ±1.5°C Temperature Sensor with multiple gain analogue output. Which operate at a supply voltage as low as 1.5V. While operating over the wide temperature range of -50 to +150°C, the LM94021 delivers an output voltage that is inversely proportional to measured temperature. The sensor's low supply current makes it ideal for battery-powered systems as well as general temperature sensing applications. Two logic inputs, Gain Select 1 (GS1) and Gain Select 0 (GS0), select the gain of the temperature-to-voltage output transfer function. Four slopes are selectable -5.5, -8.2, -10.9 and -13.6mV/°C. In the lowest gain configuration (GS1 and GS0 both tied low), This sensor can operates with a 1.5V supply while measuring temperature over the full -50 to +150°C operating range. Tying both inputs high causes the transfer function to have the largest gain of -13.6mV/°C for maximum temperature sensitivity.
