I'm trying to integrate this into a design project at my University, but I'm having difficulties understanding some of the functions. Does this product amplify through DIN1 or DIN2 pins? From what I can see the purpose of the capacitors is to smooth out the output signals, but do they need to be the capacitors listed on the datasheet? I saw a schematic that had multiple inputs running into the IC, what happens if a signal is connected to the pins that are meant for capacitors? What conversions are the RS232 lines doing? Are there any example circuit designs that can be viewed?
