SSM2250RUZ

Overview

The SSM2250RUZ is a Class AB audio power amplifier from Analog Devices, housed in a 14-TSSOP package. It delivers 1.5 W into a mono 4 Ohm bridged-tied load (BTL) or 90 mW per channel into stereo headphones. The device operates on a supply voltage range of 2.7 V to 6 V.

Feature Summary

• Class AB topology for low distortion audio amplification
• Integrated stereo headphone output capability alongside mono BTL operation
• Wide single-supply voltage operation suitable for portable applications

Applications

• Embedded electronics audio systems
• Industrial equipment with audio feedback
• Portable consumer devices requiring mono or stereo sound

Procurement Notes

Verify the specific suffix (e.g., RUZ vs REEL) against official Analog Devices documentation to confirm packaging and reel specifications. Ensure the component status is current, as some listings indicate obsolete status for certain variants. Cross-reference the 14-TSSOP package dimensions with your PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when a single IC must support both mono BTL speaker driving and stereo headphone outputs. The 2.7 V to 6 V operating range allows compatibility with standard battery-powered systems. Verify thermal performance for the 1.5 W mono output scenario within the TSSOP enclosure constraints.

Part Context

This part belongs to the SoundMAX family of audio amplifiers by Analog Devices. It is designed for embedded applications where space is limited. The SSM2250 series provides a solution for integrating high-quality audio output without external components, leveraging Class AB efficiency.
