Si826x-EVB
3. Hardware Overview and Demo
Figure 5 illustrates the connection diagram to demonstrate the Si826x-DIP8 EVB. The other footprint boards
demonstrate in a similar fashion. This demo transmits a 500 kHz (5 V peak, 50 percent duty cycle) square wave
through the ISOdriver to its output (Vo). In this example, VDD is powered by a 15 V supply. Figure 6 shows a scope
shot of CH1 (input) and CH2 (output). Note that if a user wants to evaluate an LED Emulator Input ISOdriver other
than the ones pre-populated, this can be accomplished by removing the installed device and replacing it with the
desired footprint-compatible ISOdriver device.
