LMV796/LMV797
17 MHz, Low Noise, CMOS Input, 1.8V Operational
Amplifiers
General Description
The LMV796 (Single) and the LMV797 (Dual) low noise,
CMOS input operational amplifiers offer a low input voltage
noise density of 5.8 nV/
while consuming only 1.15 mA
(LMV796) of quiescent current. The LMV796 and LMV797
are unity gain stable op amps and have gain bandwidth of 17
www.DataSheet4U.cMoHmz. The LMV796/ LMV797 have a supply voltage range of
1.8V to 5.5V and can operate from a single supply. The
LMV796/LMV797 each feature a rail-to-rail output stage ca-
pable of driving a 600Ω load and sourcing as much as 60 mA
of current.
The LMV796 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 femtoAm-
peres, and an input common mode voltage range, which
includes ground, make the LMV796 and the LMV797 ideal
for low power sensor applications.
The LMV796/LMV797 are manufactured using National’s
advanced VIP50 process and are offered in a 5-pin SOT23
and an 8-pin MSOP package respectively.
