SSM3525BCBZRL

Overview

The SSM3525BCBZRL is a fully integrated, high-efficiency mono Class D audio amplifier with digital input and digitized output of output voltage, output current, and PVDD supply. It operates from a 4.5 V to 17 V supply and delivers up to 30.2 W into a 4 Ω load at 1% THD+N. The device features a filterless Σ-Δ modulation scheme requiring no external LC filters, supports I2C control with four pin-selectable addresses, and includes built-in short-circuit, thermal protection, and pop-and-click suppression.

Feature Summary

• Filterless digital input mono Class D amplifier utilizing Sigma-Delta modulation
• Digitized output capability for output voltage, output current, and PVDD supply voltage
• Integrated analog-to-digital converters for real-time monitoring of system parameters
• User-selectable ultralow EMI emissions mode via spread spectrum pulse density modulation

Applications

• Mobile computing
• Portable electronics

Procurement Notes

Verify the specific suffix BCBZRL against the manufacturer's ordering guide to confirm package dimensions and tape/reel specifications. Ensure compatibility with the required IOVDD supply range and serial interface formats before finalizing procurement. Confirm that the component meets all environmental compliance standards relevant to the target market.

Selection Notes

Select this component for applications requiring high power output in a compact form factor without external filtering components. Consider the 23-ball WLCSP package constraints for PCB layout. Evaluate the need for digitized sensing outputs if system monitoring is required. Verify that the digital audio interface matches the source processor's capabilities.

Part Context

This part belongs to the SSM3525 family of high-efficiency audio amplifiers designed by Analog Devices Inc. The family focuses on delivering high power with minimal external components, targeting portable devices where space and battery life are critical. The SSM3525 variant specifically integrates advanced sensing and control features within a small footprint.

Replacement Considerations

Consult the official Analog Devices ordering guide for confirmed substitute part numbers. Do not assume cross-compatibility with other Class D amplifiers due to differences in pinout, control interfaces, and electrical characteristics.
