tsv912h, TSV912AH application information doc id 17688 rev 1 11/16 3 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 . 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 improv e 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. figure 18. in-series resistor vs. capacitive load 3.2 pcb layouts for correct operation, it is advised to add 10 nf decoupling capacitors as close as possible to the power supply pins.
