DESCRIPTION  
The LMV841/LMV842/LMV844 are low-voltage and  
low-power operational amplifiers that operate with  
supply voltages ranging from 2.7V to 12V and have  
rail-to-rail input and output capability. Their low offset  
voltage, low supply current, and MOS inputs make  
them ideal for sensor interface and battery-powered  
applications.  
Input offset voltage 500μV max  
Input bias current 0.3pA  
CMRR 112dB  
Input voltage noise 20nV/√Hz  
Temperature range −40°C to 125°C  
Rail-to-Rail input  
The single LMV841 is offered in the space-saving 5-  
Pin SC70 package, the dual LMV842 in the 8-Pin  
VSSOP and 8-Pin SOIC packages, and the quad  
LMV844 in the 14-Pin TSSOP and 14-Pin SOIC  
packages. These small packages are ideal solutions  
for area-constrained PC boards and portable  
electronics.  
Rail-to-Rail output  
The LMV841Q, LMV842Q, and LMV844Q are  
AEC-Q100 grade 1 qualified and are  
manufactured on automotive grade flow.  
The LMV841Q, LMV842Q, and LMV844Q incorporate  
enhanced manufacturing and support processes for  
the automotive market , including defect detection  
methodologies.  
Reliability qualification is compliant with the  
requirements and temperature grades defined in the  
AEC-Q100 standard.
