Application information
Operating voltages
The TSV85x can operate from 2.5 to 5.5 V. The devices’ parameters are fully specified for
2.7 and 5 V power supplies. Additionally, the main specifications are guaranteed in extended
temperature ranges from -40° C to +125° C.
Input common-mode range
The TSV85x have an input common-mode range that includes ground. The input common-
mode range is extended from V
Rail-to-rail output
The operational amplifiers’ output levels can go close to the rails: 180 mV maximum above
and below the rail when connected to a 10 kΩ resistive load to
Input offset voltage drift over temperature
The maximum input voltage drift over the temperature variation is defined as follows.

PCB layouts
For correct operation, it is advised to add 10 nF decoupling capacitors as close as possible
to the power supply pins.
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.
