LM94021/LM94021Q  
Multi-Gain Analog Temperature Sensor  
Disk drives  
General Description  
Games  
The LM94021 is a precision analog output CMOS integrated-  
Appliances  
circuit temperature sensor that operates at a supply voltage  
as low as 1.5V. While operating over the wide temperature  
range of −50°C to +150°C, the LM94021 delivers an output  
voltage that is inversely proportional to measured tempera-  
ture. The LM94021's low supply current makes it ideal for  
battery-powered systems as well as general temperature  
sensing applications.  
Features  
LM94021Q is AEC-Q100 Grade 0 qualified and is  
manufactured on an Automotive grade Flow  
Low 1.5V operation  
Four selectable gains  
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 mV/°C,  
−8.2 mV/°C, −10.9 mV/°C, and −13.6 mV/°C. In the lowest  
gain configuration (GS1 and GS0 both tied low), the LM94021  
can operate with a 1.5V supply while measuring temperature  
over the full −50°C to +150°C operating range. Tying both  
inputs high causes the transfer function to have the largest  
gain of −13.6 mV/°C for maximum temperature sensitivity.  
The gain-select inputs can be tied directly to VDD or Ground  
without any pull-up or pull-down resistors, reducing compo-  
nent count and board area. These inputs can also be driven  
by logic signals allowing the system to optimize the gain dur-  
ing operation or system diagnostics.  
Very accurate over wide temperature range of −50°C to  
+150°C  
Low quiescent current  
Output is short-circuit protected  
Extremely small SC70 package  
Footprint compatible with the industry-standard LM20  
temperature sensor
