SSM2250RUZ-REEL

Overview

The SSM2250RUZ-REEL is a Class AB audio power amplifier from Analog Devices, housed in a 14-pin 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 voltage supply range of 2.7 V to 6 V. Key electrical specifications include a maximum output power of 1.5 W at 8 Ohms for mono configuration. It integrates depop and shutdown features to manage audio artifacts and power consumption efficiently.

Feature Summary

• Class AB architecture optimized for low distortion audio reproduction
• Integrated depop circuitry to eliminate switching noise during power cycles
• Supports both mono speaker output and dual-channel headphone driving
• Shutdown capability for effective power management in portable devices

Applications

• Portable audio players requiring efficient mono speaker amplification
• Headphone amplifier stages in mobile communication devices
• Low-power consumer electronics with limited battery capacity
• Stereo audio output sections in compact multimedia gadgets

Procurement Notes

Verify the specific suffix REEL against official Analog Devices documentation to confirm tape-and-reel packaging status. Ensure the operating voltage range aligns with your system's power supply constraints. Cross-reference the TSSOP-14 pinout with your PCB layout requirements. Confirm RoHS compliance details through the manufacturer's current datasheet revision. Validate that the mono/stereo output configuration matches your intended application design.

Selection Notes

Select this component when a single IC must drive both a speaker and headphones in space-constrained designs. The Class AB topology offers a balance between efficiency and audio fidelity suitable for voice and music. Consider the 2.7 V to 6 V supply window to ensure compatibility with single-cell lithium batteries. The integrated protection features reduce external component count compared to discrete solutions.

Part Context

This part belongs to the SoundMAX series of audio amplifiers from Analog Devices. It is designed specifically for portable applications where power efficiency and small form factor are critical. The SSM2250 complements other audio interface components by providing robust analog output stage capabilities within a minimal footprint.

Replacement Considerations

Consult Analog Devices official substitution guides for direct replacements. Verify pin-to-pin compatibility if considering alternative packages. Ensure thermal performance characteristics match your enclosure constraints.
