Overview
The AFE032IRGZT from Texas Instruments is a low-cost, integrated power-line communications (PLC) analog front-end (AFE) device. It is designed for transformer-coupled connections to the power line and operates under the control of a digital signal processor (DSP) or microcontroller. This device is ideal for driving high-current, low-impedance lines up to 1.9 A into reactive loads, making it highly reliable in demanding power-line communication applications.
