Overview
The STLD1 line driver, produced by STMicroelectronics, is a low-distortion, high-current dual power amplifier specifically designed for power-line communication (PLC) applications. It operates on a single 8-18 V supply and is capable of delivering high output current up to 1.5 ARMS and an output voltage swing of up to 18 V peak-to-peak single-ended or 36 V peak-to-peak differential. This device is optimized for driving AC power-line loads with high efficiency and compliance with various regulatory standards such as CENELEC, FCC, and ARIB.
