LM94022, LM94022-Q1  
SNIS140F –MAY 2006–REVISED SEPTEMBER 2015  
LM94022/-Q1 1.5-V, SC70, Multi-Gain Analog Temperature Sensor With Class-AB Output  
1 Features  
3 Description  
The LM94022/-Q1 device is a precision analog output  
CMOS integrated-circuit temperature sensor with  
selectable linear negative temperature coefficient

•
•
•
LM94022/-Q1 is AEC-Q100 Grade 0 qualified and  
is Manufactured on an Automotive Grade Flow  
Low 1.5-V to 5.5-V Operation With Low 5.4-µA  
Supply Current  
(NTC).  
A class-AB output structure gives the  
LM94022/-Q1 strong output source and sink current  
capability for driving heavy transient loads such as  
that presented by the input of a sample-and-hold  
analog-to-digital converter. The low 5.4-µA supply  
current and 1.5-V operating voltage of the LM94022/-  
Q1 make it ideal for battery-powered systems as well  
as general temperature-sensing applications.  
Push-Pull Output With ±50-µA Source Current

±1.5ºC Temperature Accuracy for 20ºC to  
40ºC Range  
The Gain Select 1 (GS1) and Gain Select 0 (GS0)  
logic inputs select one of four gains for the  
temperature-to-voltage output transfer function: −5.5  
mV/°C, −8.2 mV/°C, −10.9 mV/°C, and −13.6 mV/°C.  
Selecting –5.5 mV/°C (GS1 and GS0 both tied low),  
allows the LM94022/-Q1 to operate down to 1.5-V  
supply while measuring temperature over the full  
range of −50°C to +150°C. Maximum temperature  
sensitivity, –13.6 mV/°C, is selected when GS1 and  
GS0 are both tied high. The gain-select inputs can be  
tied directly to VDD or Ground without any pullup or  
pulldown resistors, reducing 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.  
±1.8ºC Temperature Accuracy for –50ºC to  
70ºC Range  
±2.1ºC Temperature Accuracy for –50ºC to  
90ºC Range  
±2.7ºC Temperature Accuracy for –50ºC to
