SSM3302ACPZ-R7

Overview

The SSM3302ACPZ-R7 is a stereo Class-D audio amplifier utilizing filterless Σ-Δ modulation. It delivers 2 × 10 W into 4 Ω and 2 × 8 W into 8 Ω at 12 V supply with 98 dB SNR. The device operates on a single supply voltage ranging from 7 V to 18 V. It features spread spectrum pulse density modulation for reduced EMI, fully differential inputs, and an integrated 5 V regulator. Protection includes thermal shutdown and output short-circuit detection.

Feature Summary

• Filterless design using Sigma-Delta modulation eliminates the need for external LC output filters.
• Spread spectrum technology minimizes radiated electromagnetic interference emissions.
• Fully differential input architecture provides high rejection of common-mode noise.
• Integrated pop-and-click suppression circuitry prevents audible transients during power cycling.

Applications

• Portable multimedia devices requiring high efficiency and low component count
• Active subwoofer systems utilizing mono mode configuration
• Consumer electronics requiring FCC Class-B emission compliance

Procurement Notes

Verify the specific ordering suffix matches the required reel quantity and tape specifications. Confirm that the package marking aligns with the manufacturer's current revision standards. Ensure compatibility with the intended PCB footprint dimensions and thermal pad requirements for proper heat dissipation.

Selection Notes

Select this component when board space constraints prohibit the use of bulky output inductors. Choose this amplifier for applications demanding high signal-to-noise ratios without complex filtering networks. Consider the fixed input impedance feature if gain adjustments are required across multiple production units.

Part Context

This part belongs to Analog Devices' portfolio of digital input Class-D amplifiers designed for portable audio. It utilizes advanced modulation techniques to achieve high performance while maintaining a compact form factor suitable for modern consumer electronic devices.
