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
and can operate from a single supply. The
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.
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.
