The LMV791 (single) and the LMV792 (dual) low-noise, CMOS input operational amplifiers offer a low input voltage noise density of 5.8 nV/&radicHz while consuming only 1.15 mA (LMV791) of quiescent current. The LMV791 and LMV792 are unity gain stable operational amplifiers and have gain bandwidth of 17 MHz. The LMV79x have a supply voltage range of 1.8 V to 5.5 V and can operate from a single supply. The LMV79x each feature a rail-to-rail output stage capable of driving a 600-Ω load and sourcing as much as 60 mA of current.

The LMV79x 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 LMV791 and the LMV792 ideal for low-power sensor applications. The LMV79x family has a built-in enable feature which can be used to optimize power dissipation in low power applications.

The LMV791x are manufactured using TI’s advanced VIP50 process and are offered in a 6-pin SOT and a 10-pin VSSOP package respectively.
