Overview
The STLD1TR, produced by STMicroelectronics, is a dual line driver specifically designed for power-line communication (PLC) applications. This device is optimized for high output current and low distortion, making it suitable for smart metering, smart grid, and Internet of Things (IoT) applications. The STLD1TR operates on a single 8-18 V supply and can deliver high output current up to 1.5 ARMS with an output voltage swing of up to 18 V peak-to-peak single-ended or 36 V peak-to-peak differential. It features very high linearity for EMC compliance and has an externally configurable power amplifier topology.
