The TPS2661EVM allows reference circuit evaluation of TPS26611 and TPS26612 current-loop protectors. The TPS2661 product is a 50-V, universal (±20-mA, 0-mA to 20-mA, 4-mA to 20-mA) current-loop protector with integrated fixed bipolar 30-mA current limit and output overvoltage protection. The product provides protection against miswiring conditions on input/output and offers robust signal line protection in industrial and process automation systems.
