SSM2250RMZ-R2

Overview

The SSM2250RMZ-R2 is a Class AB audio power amplifier manufactured by Analog Devices Inc. It delivers 1.5 W of low distortion power into a mono 4 Ohm bridged-tied load (BTL) or 90 mW into stereo loads. The device features an integrated thermal shutdown circuit and short-circuit protection to ensure robust operation. It operates from a single supply voltage, typically ranging from 2.7 V to 30 V, with a quiescent current of 300 µA. The component is housed in a compact 8-MSOP package, suitable for space-constrained portable audio applications.

Feature Summary

• Integrated thermal shutdown and short-circuit protection for enhanced reliability
• Low quiescent current consumption for extended battery life
• Single-supply operation capability simplifying system design

Applications

• Portable audio players
• Mobile phone speaker amplification
• Personal media devices

Procurement Notes

Verify the specific suffix 'R2' indicates reel packaging and confirm current availability status as some sources list this variant as obsolete. Ensure compatibility with existing PCB footprints for the 8-MSOP package. Cross-reference the manufacturer's official documentation for any updates on lifecycle status or recommended replacements before finalizing procurement plans.

Selection Notes

Select this component for applications requiring moderate output power in a small form factor. Consider the 8-MSOP package size relative to board space constraints. Evaluate the thermal performance requirements against the integrated protection features. Verify that the supply voltage range aligns with the system's power architecture and that the Class AB efficiency meets the device's power budget requirements.
