8V Operational Amplifiers General Description The LMV796 (Single) and the LMV797 (Dual) low noise, CMOS input operational amplifiers offer a low input voltage while consuming only 1.
15 mA noise density of 5.
8 nV/ (LMV796) of quiescent current.
The LMV796 and LMV797 are unity gain stable op amps and have gain bandwidth of 17 www.

com 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 mA 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 femtoAmperes, and an input common 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.
