SSM6515BCBZRL

Overview

The SSM6515BCBZRL is a fully integrated, high-efficiency mono Class-D audio amplifier with digital input designed for wireless headphones. It operates from a single 1.8 V supply and delivers 80 mW output power into a 16 Ω load at less than 0.1% THD+N. The device features a filterless design using spread spectrum Σ-Δ modulation to minimize EMI. It supports I2S, TDM, and PDM inputs, includes micropower shutdown mode, pop-click suppression, and short-circuit protection.

Feature Summary

• Filterless digital input utilizing stable common-mode pulse density modulation
• Integrated digital gain adjustment and programmable DC blocking high-pass filter
• Micropower shutdown mode with automatic clock-loss detection
• Built-in output short-circuit protection and overtemperature warning

Applications

• Wireless headphones
• Active noise-canceling (ANC) earbuds
• Portable digital audio players
• Bluetooth audio receivers
