Description
The TSV85x series of single, dual and quad
operational amplifiers offers low voltage operation
with a rail-to-rail output swing. The TSV85x series
outperforms the industry standard LMV321,
proposing lower supply voltage capability,
enhanced input offset voltage and smaller
packages.

... Macromodel Accurate macromodels of the TSV85x 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 TSV85x 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 ...
