SSM2517CBZ-RL

Overview

The SSM2517CBZ-RL is a mono Class-D audio amplifier with a PDM digital input, manufactured by Analog Devices Inc. It delivers 2.4 W into a 4 Ω load and 1.38 W into an 8 Ω load at a 5.0 V supply voltage, maintaining less than 1% total harmonic distortion plus noise (THD + N). The device operates with a PVDD range of 2.5 V to 5.5 V and a VDD range of 1.62 V to 3.6 V. It features 92% efficiency into an 8 Ω load at full scale and includes pop-and-click suppression. Packaged in a 9-ball, 1.5 mm × 1.5 mm WLCSP, it supports 64× or 128× fS operation.

Feature Summary

• Integrates a digital-to-analog converter, power amplifier, and PDM interface on a single chip for low system noise.
• Utilizes spread-spectrum pulse density modulation to minimize electromagnetic interference emissions.
• Features smart power-down functionality that activates automatically upon detection of PDM stop conditions or missing clock inputs.
• Includes built-in thermal shutdown and output short-circuit protection with autorecovery capabilities.

Applications

• Mobile handsets
• Portable media players

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging configuration. Confirm that the component meets all required environmental standards and temperature ratings specified in the datasheet before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring high-efficiency digital audio amplification with minimal external passive components. Ensure the system design accommodates the dual power supply requirements and utilizes the GAIN_FS pin to optimize performance for either 3.6 V or 5 V operating voltages.

Part Context

This part belongs to the SSM2517 series of PDM digital input Class-D amplifiers. It is designed to replace traditional DAC plus Class-D solutions by integrating the audio conversion and amplification stages. The device is optimized for power-sensitive portable electronics where reducing analog signal corruption from digital noise sources is critical.
