SSM2518CPZ-RL

Overview

The SSM2518CPZ-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 and 1.4 W into 8 Ω at 5 V supply with 1% THD+N. It supports I2C control or standalone operation, featuring a wide dynamic range compression engine, pop-and-click suppression, and ultralow EMI modes. Operating temperatures range from -40°C to +85°C.

Feature Summary

Filterless digital architecture combining DAC and sigma-delta modulation for direct digital audio processing
Programmable dynamic range compression with noise gate, expander, compressor, and limiter functions
Integrated smart power-down and automatic sample rate detection capabilities
User-selectable ultralow EMI emission mode to minimize electromagnetic interference

Applications

Mobile phones
Portable media players
Laptop PCs
Wireless speakers
Navigation systems

Procurement Notes

Verify the specific CPZ-RL suffix against the manufacturer's current ordering guide to confirm package type and reel specifications. Ensure compatibility with system voltage rails (PVDD 2.5 V to 5.5 V; DVDD 1.62 V to 3.6 V). Confirm thermal management requirements for the LFCSP package in the target enclosure design before finalizing procurement.

Selection Notes

Select this component for applications requiring high efficiency and low power consumption from digital audio sources. It is suitable where system noise immunity is critical, as the digital interface reduces susceptibility to GSM interference. Consider the integrated DRC and volume control features if external DSP resources are limited.

Part Context

This part belongs to the SSM2518 family of digital input Class-D amplifiers. It is designed to replace traditional DAC plus analog amplifier solutions by integrating both functions on a single chip. The CPZ-RL designation indicates the 20-lead LFCSP package variant supplied in tape and reel format.
