Description
The LMV82x series of single, dual and quad
operational amplifiers offers low voltage operation
with rail-to-rail output swing. The LMV82x series
outperforms the industry standard LMV321
especially with regard to the gain bandwidth
product (5.5 MHz). The LMV821, LMV822 and
LMV824 are proposed with standard pinouts.

... Macromodel Accurate macromodels of the LMV82x are available on STMicroelectronics’ web site at www.st.com. This model is a trade-off between accuracy and complexity (that is, time simulation) of the LMV82x operational amplifiers. It emulates the nominal performances of a typical device within the specified operating conditions mentioned in the datasheet. It also helps to validate a design approach and to select the right operational amplifier, but it does not replace on-board measurements ...
