illustrate
The LMV791 (single) and LMV792 (dual) low-noise, CMOS input op-amps provide a low input voltage noise density of 5.8 NV/situ while consuming only 1.15 mA (LMV791) of quiescent current. The LMV791 and LMV792 are unity-gain stable op-amps with a gain bandwidth of 17 MHz. The LMV791/LMV792 has a supply voltage range of 1.8V to 5.5V and can be operated from a single supply. The LMV791/LMV792 are each functional rail-to-rail output stage capable of driving 600Ω loads and procuring currents up to 60 mA.
The LMV791 home provides optimal performance for low-voltage and low-noise systems. The CMOS input stage, with typical input bias currents in several femtoAmperes ranges, input common-mode voltage ranges, including ground makes the LMV791 and LMV792 ideal for low-power sensor applications. The LMV791 has a built-in enabled feature that can be used to optimize power consumption in low-power applications.
The LMV791/LMV792 are manufactured using the state-advanced VIP50 process and are available in 6-pin TSOT23 and 10-pin MSOP packages, respectively.
