SSM2302CPZ-R2

Overview

The SSM2302CPZ-R2 is a fully integrated, high-efficiency Class-D stereo audio amplifier designed for mobile phone applications. It delivers 1.4 W into an 8 Ω load at 5.0 V supply with less than 1% THD+N. The device operates from a single 2.5 V to 5.0 V supply and achieves 85% efficiency at full power. It features a signal-to-noise ratio better than 98 dB and utilizes PDM modulation for lower EMI emissions. The component includes built-in resistors, pop-and-click suppression, and ultralow shutdown current of 20 nA.

Feature Summary

Filterless Class-D architecture with built-in output stage reduces external component count
Sigma-delta modulation scheme minimizes EMI radiated emissions compared to PWM architectures
Integrated pop-and-click suppression ensures noiseless activation and deactivation
Built-in thermal shutdown and output short-circuit protection enhance reliability

Applications

Mobile phones
MP3 players
Portable gaming devices
Educational toys

Procurement Notes

Verify the obsolete status of this component before procurement planning. Confirm availability through authorized distributors or secondary markets as standard production may have ceased. Ensure compatibility with existing PCB footprints and design specifications if integrating into new hardware revisions.

Selection Notes

Select this amplifier for portable electronics requiring high efficiency and minimal board space. The filterless design simplifies layout and reduces system cost. Consider the 2.5 V to 5.0 V operating range for battery-powered applications. Verify gain configuration requirements against the fixed internal resistor options or external adjustment capabilities.

Part Context

The SSM2302 belongs to Analog Devices' line of high-efficiency Class-D audio amplifiers. It is packaged in a 16-lead, 3 mm × 3 mm LFCSP. The CPZ suffix indicates a lead-free package compliant with RoHS standards. The -R2 suffix denotes the specific reel packaging format for surface-mount assembly.
