FEATURES  
DESCRIPTION  
The LMV796/LMV796Q (Single) and the LMV797  
(Dual) low noise, CMOS input operational amplifiers  
offer a low input voltage noise density of 5.8 nV/√Hz  
while consuming only 1.15 mA (LMV796/LMV796Q)  
of quiescent current. The LMV796/LMV796Q and  
LMV797 are unity gain stable op amps and have gain  
bandwidth of 17 MHz. The LMV796/LMV796Q/  
LMV797 have a supply voltage range of 1.8V to 5.5V

LMV796/LMV796Q/LMV797 each feature a rail-to-rail  
output stage capable of driving a 600Ω load and  
sourcing as much as 60 mA of current.

The LMV796/LMV796Q family provides optimal  
performance in low voltage and low noise systems. A  
CMOS input stage, with typical input bias currents in  
the range of a few femtoAmperes, and an input  
common mode voltage range, which includes ground,  
make the LMV796/LMV796Q and the LMV797 ideal  
for low power sensor applications.

LMV796Q is an Automotive Grade Product that  
is AEC-Q100 Grade 1 Qualified and is  
Manufactured on an Automotive Grade Flow.  
The LMV796/LMV796Q/LMV797 are manufactured  
using TI’s advanced VIP50 process. The LMV796/  
LMV796Q are offered in 5–pin SOT-23 package. The  
LMV797 is offered in 8–pin VSSOP package.
