... Figure 29. FIGURE 29. LIMITING THE INPUT CURRENT TO LESS THAN Using Only One Channel The ISL28291 is a Dual channel op amp. If the application only requires one channel when using the ISL28291, the user must configure the unused channel to prevent it from oscillating. Oscillation can occur if the input and output pins are floating ...
