LMV797 Datasheet | National Semiconductor

Description The LMV796 (Single) and the LMV797 (Dual) low noise, CMOS input operational amplifiers offer a low input voltage while consuming only 1.15 m A noise density of 5.8 n V/ (LMV796) of quiescent current. The LMV796 and LMV797 are unity gain stable op amps and have gain bandwidth of 17 .. MHz. The LMV796/ LMV797 have a supply voltage range of 1.8V to 5.5V and can operate from a single supply. The LMV796/LMV797 each feature a rail-to-rail output stage capable of driving a 600Ω load and sourcing as much as 60 m A of current. The LMV796 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 femto Amperes, and an input mon mode voltage range, which includes ground, make the LMV796 and the LMV797 ideal for low power sensor applications. The LMV796/LMV797 are manufactured using National’s advanced VIP50 process and are offered in a 5-pin SOT23 and an 8-pin MSOP package respectively.
