1 Introduction

The TPS2661EVM allows reference circuit evaluation of the TPS26610 and TPS26612 current-loop protector from TI. The TPS2661x device is a 50-V, universal (±20 mA, 0 to 20 mA, 4–20 mA) current-loop protector with integrated fixed bipolar 30-mA current limit and output overvoltage protection. The device provides protection against miswiring conditions on input/output and offers robust signal-line protection in industrial and process automation systems.
