LMV793/LMV794
88 MHz, Low Noise, 1.8V CMOS Input, Decompensated
Operational Amplifiers
General Description
The LMV793 (single) and the LMV794 (dual) CMOS input
operational amplifiers offer a low input voltage noise density
of 5.8 nV/
while consuming only 1.15 mA (LMV793) of
quiescent current. The LMV793/LMV794 are stable at a gain
of 10 and have a gain bandwidth product (GBW) of 88 MHz.
The LMV793/LMV794 have a supply voltage range of 1.8V to
5.5V and can operate from a single supply. The LMV793/
LMV794 each feature a rail-to-rail output stage capable of
driving a 600
load and sourcing as much as 60 mA of cur-
rent.
The LMV793/LMV794 provide optimal performance in low
voltage and low noise systems. A CMOS input stage, with
typical input bias currents in the range of a few femto-Am-
peres, and an input common mode voltage range, which
includes ground, make the LMV793/LMV794 ideal for low
power sensor applications where high speeds are needed.
The LMV793/LMV794 are manufactured using National’s ad-
vanced VIP50 process. The LMV793 is offered in either a 5-
Pin SOT23 or an 8-Pin SOIC package. The LMV794 is offered
in either the 8-Pin SOIC or the 8-Pin MSOP.
