Product Introduction

Overview

The SSM2518CPZ-RL is a fully integrated, 2-channel digital input, Class-D audio power amplifier produced by Analog Devices Inc. This device is designed to receive digital audio input and produce PDM (Pulse Density Modulation) differential switching outputs using its internal power stage. It features built-in protection for overtemperature and overcurrent conditions, as well as soft turn-on and turn-off capabilities to suppress pop-and-click noises. The amplifier supports a 2-wire serial (I2C-compatible) microprocessor bus for programmable register control.
