DESCRIPTION
The LMV793 (single) and the LMV794 (dual) CMOS
input operational amplifiers offer a low input voltage
noise density of 5.8 nV/√Hz 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 600Ω load and
sourcing as much as 60 mA of current.
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-Amperes, 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 TI’s
advanced 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 VSSOP.
