Application information

3.1

Driving resistive and capacitive loads

These products are low-voltage, low-power operational amplifiers optimized to drive rather

large resistive loads above 2 k

Ω.

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 in-series

resistor at the output can improve the stability of the devices (see Figure 18 for

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.
