The smaller EVM version shows the customer the space required for their design. This circuit provides an isolated, 40 Mbps, 3.3V to 5V Profibus interface using the ISO1176T, isolated Profibus transceiver and the TPS high accuracy linear regulator. The circuit achieves signal and power isolation and at the same time decrease board space and power consumption.
