General Description  
The LM94022 is  
a precision analog output CMOS  
integrated-circuit temperature sensor that operates at a sup-  
ply voltage as low as 1.5 Volts. A class-AB output structure  
gives the LM94022 strong output source and sink current  
capability for driving heavy loads. For example, it is well  
suited to source the input of a sample-and-hold analog-to-  
digital converter with its transient load requirements. While  
operating over the wide temperature range of −50˚C to  
+150˚C, the LM94022 delivers an output voltage that is  
inversely porportional to measured temperature. The  
LM94022’s low supply current makes it ideal for battery-  
powered systems as well as general temperature sensing  
applications.  
Features  
n Low 1.5V operation  
n Push-pull output with 50µA source current capability  
n Four selectable gains  
n Very accurate over wide temperature range of −50˚C to  
+150˚C  
n Low quiescent current  
n Output is short-circuit protected  
n Extremely small SC70 package  
n Footprint compatible with the industry-standard LM20  
temperature sensor  
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  
LM94022 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, reduc-  
ing component count and board area. These inputs can also  
be driven by logic signals allowing the system to optimize the  
gain during operation or system diagnostics.
