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.
These operational 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 TSV62x (29 µA, 420 kHz) or TSV63x (60 µA, 880 kHz) which are
unity gain stable.
Table 8.
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 TSV6390 and TSV6391 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 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.
