In a follower configuration, these operational amplifiers can drive capacitive loads up to
100 pF with no oscillations. When driving larger capacitive loads, adding an in-series
resistor at the output can improve the stability of the devices (see
recommended in-series resistor values). Once the in-series resistor value has been
selected, the stability of the circuit should be tested on bench and simulated with the
simulation model.

PCB layouts
For correct operation, it is advised to add 10 nF decoupling capacitors as close as possible
to the power supply pins.
Macromodel
An accurate macromodel of the TSV61x 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 TSV61x 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.
