STLD1TR

Power Management - Specialized Overview

The STLD1TR is a low-distortion, high-current dual power-line communication line driver designed for narrow-band PLC applications. Operating on a single 8 V to 18 V supply, it delivers up to 1.5 A RMS output current with an 18 V p-p single-ended or 36 V p-p differential output range. The device features very high linearity for EMC compliance and externally configurable amplifier topology. It operates within a -40 °C to +105 °C temperature range and includes embedded overtemperature protection. The component is housed in a QFN24 package measuring 4x4x1 mm.
