SSM3515CCBZ-RL

Overview

The SSM3515CCBZ-RL is a fully integrated, high-efficiency mono Class-D audio amplifier with digital inputs. It operates from a single 4.5 V to 17 V supply and delivers up to 31.3 W into a 4 Ω load at 1% THD+N when powered by 17 V. The device features a filterless modulation scheme requiring no external LC output filters. It supports I2C control, flexible gain adjustment, and includes pop and click suppression. The component is housed in a 20-ball, 1.8 mm × 2.2 mm WLCSP package.

Feature Summary

• Filterless digital input mono Class-D amplifier architecture
• Integrated I2C control interface with selectable addresses
• Pop and click suppression circuitry for glitch minimization
• User-selectable ultralow EMI emissions mode

Applications

• Notebooks
• Portable electronics
• Home audio systems

Procurement Notes

Verify the specific ordering suffix CCBZ-RL against the manufacturer's current datasheet to confirm package type and reel specifications. Ensure compatibility with system voltage ranges between 4.5 V and 17 V. Confirm thermal management requirements for the WLCSP package under maximum power conditions.

Selection Notes

Select this component for applications requiring high efficiency without external output filters. It is suitable for designs needing direct digital audio inputs to eliminate external DACs. Consider the 20-ball WLCSP package size for space-constrained portable devices. Verify support for required serial data formats such as TDM16 or I2S.

Part Context

The SSM3515 belongs to Analog Devices' line of high-efficiency digital input Class-D amplifiers. It is designed to simplify application circuits by minimizing external components. The device integrates a sigma-delta modulator and full-bridge power stage within a compact wafer-level chip scale package.
