FEATURES DESCRIPTION
LM94021Q is AEC-Q100 Grade 0 Qualified and The LM94021 is a precision analog output CMOS integrated-circuit temperature sensor that operates at is Manufactured on an Automotive Grade Flow a supply voltage as low as 1.5V. While operating over, Low 1.5V Operation the wide temperature range of −50°C to +150°C, the Four Selectable Gains LM94021 delivers an output voltage that is inversely proportional to measured temperature. The Very Accurate Over Wide Temperature Range LM94021's low supply current makes it ideal for of −50°C to +150°C battery-powered systems as well as general Low Quiescent Current temperature sensing applications. Output is Short-Circuit Protected Two logic inputs, Gain Select 1 (GS1) and Gain Extremely Small SC70 Package Select 0 (GS0), select the gain of the temperature to Footprint Compatible with the Industry voltage output transfer function.
Four slopes are Standard LM20 Temperature Sensor selectable: −5.5 mV/°C, −8.2 mV/°C, −10.9 mV/°C, and −13.6 mV/°C. In the lowest gain configuration UL Recognized Component (GS1 and GS0 both tied low), the LM94021 can operate with a 1.5V supply while measuring APPLICATIONS temperature over the full −50°C to +150°C operating , Cell Phones range. Tying both inputs high causes the transfer function to have the largest gain of −13.6 mV/°C for Wireless Transceivers maximum temperature sensitivity The gain-select . Battery Management inputs can be tied directly to VDD or Ground without Automotive any pull-up or pull-down resistors, reducing component count and board area. These inputs can Disk Drives also be driven by logic signals allowing the system to Games optimize the gain during operation or system Appliances diagnostics.
