SSM2529ACBZ-RL

Overview

The SSM2529ACBZ-RL is a digital input, mono Class-D audio power amplifier integrating a DAC, DSP, and sigma-delta modulator. It operates on a single supply voltage ranging from 2.5 V to 5.5 V for SPKVDD and 1.08 V to 1.98 V for DVDD. Output power reaches 2.4 W into 4 Ω and 1.4 W into 8 Ω at 5 V supply with 1% THD. The device supports sample rates from 8.0 kHz to 96.0 kHz via I2S, PCM, TDM, or PDM interfaces. Digital volume control spans −70 dB to +24 dB in 0.375 dB steps. It includes a 7-band equalizer, dynamic range compression, and speaker protection.

Feature Summary

• Integrates a digital-to-analog converter, low-power audio DSP, and sigma-delta Class-D modulator for direct digital audio processing.
• Features a flexible serial digital audio interface supporting multiple formats including I2S, PCM, TDM, and PDM.
• Includes programmable digital signal processing such as a seven-band equalizer and dynamic range compression with noise gate.
• Provides comprehensive protection mechanisms including short-circuit, thermal shutdown with autorecovery, and pop-and-click suppression.

Applications

• Mobile phones
• Portable media players
• Laptop PCs
• Wireless speakers
• Navigation systems

Procurement Notes

Verify the specific ordering suffix matches the required tape and reel configuration. Confirm that the component revision aligns with current design specifications. Ensure compatibility with the intended operating temperature range of −40°C to +85°C. Validate pinout alignment for the 16-ball WLCSP package during PCB layout review.

Selection Notes

Select this component for applications requiring direct digital audio inputs to minimize analog noise susceptibility. Consider the integrated DSP features if system-level equalization or dynamic range control is needed without external processors. Evaluate the single-supply architecture benefits for battery-operated devices where generating separate digital and analog supplies is undesirable.
