SSM2518CBZ-RL

Overview

The SSM2518CBZ-RL is a digital input, stereo Class-D audio power amplifier manufactured by Analog Devices Inc. It integrates a DAC and sigma-delta modulator to process serial digital audio directly. The device delivers 2 W into 4 Ω or 1.4 W into 8 Ω at 5 V supply with 1% THD+N. It supports I2C control and standalone operation, featuring pop-and-click suppression, programmable dynamic range compression, and ultralow EMI modes. Operating voltages include PVDD from 2.5 V to 5.5 V and DVDD from 1.62 V to 3.6 V.

Feature Summary

Filterless digital architecture combining DAC and sigma-delta modulation for direct digital audio processing
Supports multiple serial audio formats including I2S, left/right justified, TDM, and PCM
Integrated I2C control interface with user-selectable ultralow EMI emission mode
Built-in protection mechanisms including short-circuit, thermal shutdown, and smart power-down

Applications

Mobile phones
Portable media players
Laptop PCs
Wireless speakers
Navigation systems

Procurement Notes
