SSM2211CP-REEL7

Overview

The SSM2211CP-REEL7 is a low distortion, 1.5 W audio power amplifier manufactured by Analog Devices Inc. It operates on a single supply voltage ranging from 2.7 V to 5.5 V and delivers 1 W rms into an 8 Ω load or 1.5 W rms into a 4 Ω load. The device features a 4 MHz bandwidth with total harmonic distortion plus noise below 0.2% at 1 W output. It includes a shutdown mode that reduces quiescent current to approximately 1 µA. The component is housed in an 8-lead Lead Frame Chip Scale Package (LFCSP) and supports operation across a temperature range of -40°C to +85°C.

Feature Summary

• Delivers high performance audio power with low distortion characteristics suitable for demanding audio applications.
• Features a bridged-tied load (BTL) output configuration that eliminates the need for large DC blocking capacitors.
• Incorporates a shutdown control pin to significantly reduce power consumption during standby periods.
• Provides excellent phase margin stability without requiring external compensation components.

Applications

• Portable computers
• Personal wireless communicators
• Hands-free telephones
• Speaker phones
• Intercoms

Procurement Notes

Verify the specific package suffix CP indicates the LFCSP variant rather than the SOIC option when sourcing. Confirm the REEL7 designation matches the required tape and reel quantity for automated assembly processes. Ensure the manufacturer part number aligns exactly with the requested specifications to avoid functional discrepancies between package types.

Selection Notes

Select this component for designs requiring a single-supply audio solution with minimal external passive components. The LFCSP package offers superior thermal performance compared to standard surface mount options. Consider the BTL topology benefits for maximizing speaker efficiency and sound pressure levels within low voltage constraints.

Part Context

This component belongs to the SSM2211 family of audio amplifiers designed for portable electronics. The CP suffix specifically denotes the 8-lead LFCSP package, which provides enhanced thermal dissipation capabilities relative to other available packages in the series. This packaging choice supports higher power delivery while maintaining reliable operation in compact form factors.
