SSM6515BCBZRL7

Overview

The SSM6515BCBZRL7 is a fully integrated, high-efficiency mono Class-D audio amplifier with digital input. It operates from a single 1.8 V PVDD supply and a 1.2 V to 1.8 V IOVDD supply. The device delivers 80 mW output power into a 16 Ω load at less than 0.1% THD+N. It features a filterless design using spread spectrum common-mode pulse density modulation for low EMI. Key specifications include an A-weighted SNR of 113 dB, idle current of 0.85 mA in I2S mode, and shutdown current of 6 μA.

Feature Summary

• Filterless digital input utilizing stable common-mode pulse density modulation
• Integrated micropower shutdown mode with automatic clock loss detection
• Supports I2C control interface or standalone operation without external microcontrollers
• Built-in pop and click suppression circuitry for glitch-free startup

Applications

• Wireless headphones
• Active noise-cancelling (ANC) earbuds
• Portable digital audio players
• Smart speakers and voice assistants

Procurement Notes

Verify the specific suffix BCBZRL7 against the manufacturer's ordering guide to confirm package dimensions and reel quantities. Ensure compatibility with the EVAL-SSM6515Z evaluation board for initial system validation. Confirm RoHS compliance status through official documentation before finalizing procurement.

Selection Notes

Select this component for applications requiring minimal external components due to its filterless architecture. It is suitable for battery-powered devices given its ultra-low power consumption modes. Verify that the host processor supports the required serial audio formats, such as I2S, TDM, or PDM, for proper integration.

Part Context

This part belongs to the Analog Devices SSM6515 series of ultra-low power Class-D amplifiers. It is designed specifically for mobile audio applications where space and power efficiency are critical constraints. The device integrates a DAC and digital signal processing capabilities directly into the amplifier stage.

Replacement Considerations

Direct replacements within the same family include the SSM6515BCBZ. Verify pinout compatibility and electrical specifications when substituting parts from other manufacturers.
