SSM2211CPZ-R2

Overview

The SSM2211CPZ-R2 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 portable applications.
• Features a bridged-tied load (BTL) differential output configuration that eliminates the need for large DC blocking capacitors.
• Incorporates a shutdown control pin to significantly reduce power consumption during standby periods.
• Operates stably with wide phase margin and excellent power supply rejection ratios.

Applications

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

Procurement Notes

Verify the specific suffix CPZ against the manufacturer's ordering guide to confirm the LFCSP package type and reel quantity. Ensure compatibility with the required thermal management strategy, as the exposed pad must be connected to ground for optimal heat dissipation. Cross-reference the revision history to confirm the datasheet version matches the production batch specifications.

Selection Notes

Select this component when designing low-voltage audio systems requiring up to 1.5 W output without external coupling capacitors. Consider the LFCSP package for superior thermal performance compared to standard SOIC options. Evaluate the shutdown functionality if battery life extension is a critical design parameter for the target application.

Part Context

This part belongs to the SSM2211 family of audio amplifiers designed for unregulated battery-powered applications. The CPZ suffix specifically denotes the 8-lead LFCSP surface-mount package variant. This packaging option provides lower junction-to-ambient thermal resistance, enhancing reliability and performance under high-power conditions compared to traditional narrow-body packages.
