LM94021Qis AEC-Q100 Grade0 Qualified and integrated-circuit temperature sensor that operatesat
is Manufactured onan Automotive Grade Flow a supply voltageas lowas 1.5V. While operating over
• Low 1.5V Operation the wide temperature rangeof −50°Cto +150°C, the
Four Selectable Gains LM94021 delivers an output voltage thatis inversely
proportional to measured temperature. The
• Very Accurate Over Wide Temperature Range LM94021's low supply current makesit ideal for
of −50°Cto +150°C battery-powered systems as well as general
• Low Quiescent Current temperature sensing applications.
Outputis Short-Circuit Protected Two logic inputs, Gain Select1 (GS1) and Gain
• Extremely Small SC70 Package Select0 (GS0), select the gainof the temperature-to-
voltage output transfer function. Four slopes are
• Footprint Compatible with the Industry-selectable: −5.5 mV/°C, −8.2 mV/°C, −10.9 mV/°C,
Standard LM20 Temperature Sensor 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°Cto +150°C operating
range. Tying both inputs high causes the transfer
• Cell Phones functionto have the largest gainof −13.6 mV/°C for
• Wireless Transceivers maximum temperature sensitivity. The gain-select
• Battery Management inputs can be tied directlyto VDDor Ground without
any pull-up or pull-down resistors, reducing
• Automotivecomponent count and board area. These inputs can
• Disk Drives alsobe drivenby logic signals allowing the systemto
• Games optimize the gain during operation or system
Appliances diagnostics.
