Optimization of DC and AC parameters
These devices use an innovative approach to reduce the spread of the main DC and AC
parameters. An internal adjustment achieves a very narrow spread of the current
consumption (60 µA typical, min/max at
consumption value, such as GBP, SR and A

Driving resistive and capacitive loads
These products are micropower, low-voltage operational amplifiers optimized to drive rather
large resistive loads, above 2 kΩ .. For lower resistive loads, the THD level may significantly
increase.
The amplifiers have a relatively low internal compensation capacitor, making them very fast
while consuming very little. They are ideal when used in a non-inverting configuration or in
an inverting configuration in the following conditions.

As these operational amplifiers are not unity gain stable, for a low closed-loop gain, it is
recommended to use the TSV63x (60 µA, 880 kHz) which is unity gain stable.

PCB layouts
For correct operation, it is advised to add 10 nF decoupling capacitors as close as possible
to the power supply pins.
4.8
Macromodel
Two accurate macromodels (with or without shutdown feature) of the TSV639x 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 TSV639x 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.
