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 AVd, benefit from this narrow dispersion. All parts
present a similar speed and the same behavior in terms of stability. In addition, the minimum
values of GBP and SR are guaranteed (GBP = 730 kHz minimum and SR = 0.25 V/µs
minimum).
Driving resistive and capacitive loads
These products are micro-power, low-voltage operational amplifiers optimized to drive rather
large resistive loads, above 2 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 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.
