... Application information 3.1 Operating voltages The TSV620 and TSV621 can operate from 1.5 to 5.5 V. Their parameters are fully specified for 1.8, 3.3 and 5 V power supplies. However, the parameters are very stable in the full V range and several characterization curves show the TSV62x characteristics at 1.5 V. Additionally, the main specifications are guaranteed in extended temperature ranges from -40° ...

... TSV620, TSV620A, TSV621, TSV621A 3.8 Macromodel An accurate macromodel of TSV620-TSV621 is 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 TSV62x operational amplifiers. It emulates the nominal performances of a typical device within the specified operating conditions mentioned in the datasheet. It helps to validate a design approach and to select the right operational amplifier, but it does not replace on-board measurements ...
