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.
