SSM2211CP-REEL

Overview

The SSM2211CP-REEL 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 drain to approximately 100 nA. The component is housed in an 8-lead LFCSP surface-mount package and functions within 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.
• Incorporates a differential bridged-tied load (BTL) output configuration that eliminates the need for large DC blocking capacitors.
• Features a dedicated shutdown control pin that significantly extends battery life by minimizing quiescent current consumption.
• Operates reliably across a wide temperature range and supports single-supply operation down to 1.75 V.

Applications

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

Procurement Notes

Verify the specific suffix CP indicates the Lead Frame Chip Scale Package (LFCSP) variant rather than the SOIC version. Confirm the REEL designation matches the required tape and reel quantity for automated assembly processes. Ensure the ordering code aligns with the manufacturer's current revision G datasheet specifications to guarantee compatibility with intended circuit designs.

Selection Notes

Select this component when designing low-voltage audio systems requiring up to 1.5 W of output power. It is appropriate for battery-operated devices where extended runtime is critical due to its low standby current. Consider the thermal resistance of the LFCSP package for heat dissipation requirements in compact enclosures compared to standard packaging options.

Part Context

This part belongs to the SSM2211 family of audio amplifiers designed for portable electronics. The CP suffix specifically denotes the 8-lead LFCSP package, which offers improved thermal performance relative to the SOIC variant. The REEL suffix indicates it is supplied in continuous tape and reel format for high-volume manufacturing.

FAQ

Does the SSM2211 require external compensation capacitors?

No, the SSM2211 is unity-gain stable and does not require external compensation capacitors for operation.

How does the BTL configuration benefit the speaker connection?

The bridged output configuration doubles the voltage swing across the load and eliminates the need for a large output coupling capacitor, as the DC bias at both outputs is equal.
