... C Registers FIGURE 4. CURRENT DRIVE MODE OPTIONS When the IR from the LED reaches an object and gets reflected back into the ISL29028, the reflected IR light is converted into current as per the IR spectral response shown in Figure 7. One entire proximity measurement takes 0.54ms for one conversion (which includes 0.1ms ...

Like other I performance even in significantly noisy environments. There are only a few considerations that will ensure best performance. Route the supply and I sources of noise. A 0.1µF and 1µF power supply decoupling capacitors need to be placed close to the device ...
