Driving resistive and capacitive loads
These products are micro-power, low-voltage operational amplifiers optimized to drive rather
large resistive loads, above 5 kΩ . For lower resistive loads, the THD level may significantly
increase.
In a follower configuration, these operational amplifiers can drive capacitive loads up to
100 pF with no oscillations. When driving larger capacitive loads, adding a small resistor in
series at the output can improve the stability of the device (see
in-series resistor values). Once the value of the in-series resistor 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
Two accurate macromodels (with or without shutdown feature) of TSV62x 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 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.
