SSM2301RMZ-R2

Overview

The SSM2301RMZ-R2 is a mono Class-D audio amplifier from Analog Devices, packaged in an 8-lead Mini Small Outline Package (MSOP). It operates on a single supply voltage ranging from 2.5 V to 5.0 V and delivers up to 1.4 W of continuous output power into an 8 Ω load at 5.0 V with less than 1% THD+N. The device utilizes Σ-Δ modulation for filterless operation, achieving 85% efficiency at full power and offering a signal-to-noise ratio greater than 98 dB. It features ultralow shutdown current, pop-and-click suppression, and built-in thermal and short-circuit protection.

Feature Summary

• Filterless design using Sigma-Delta modulation eliminates the need for external LC output filters.
• Integrated pop-and-click suppression minimizes audible transients during power-up and power-down cycles.
• Micropower shutdown mode significantly reduces standby current consumption.
• Built-in protection mechanisms include thermal shutdown and output short-circuit safety.

Applications

• Mobile phones
• MP3 players
• Portable gaming devices
• Educational toys

Procurement Notes

Verify that the specific ordering suffix matches the required package type and reel configuration. Confirm RoHS compliance status as indicated by the 'Z' designation in the part number. Ensure the temperature range aligns with commercial specifications. Cross-reference the manufacturer's latest datasheet revision to confirm pinout consistency and any potential updates to absolute maximum ratings or electrical characteristics before finalizing procurement.

Selection Notes

Select this component when board space conservation is critical due to its filterless architecture. It is suitable for applications requiring high efficiency and low noise performance from a single low-voltage supply. Consider the gain control options and input configuration flexibility. Evaluate thermal management requirements based on the MSOP package thermal resistance. Ensure the application environment falls within the specified commercial operating temperature range.

Part Context

This part belongs to the SSM2301 family of high-efficiency mono Class-D amplifiers. The RMZ suffix specifically denotes the 8-lead Mini Small Outline Package variant. Other variants in the series include LFCSP packages. The device is designed to maximize performance in mobile phone applications while minimizing external component count.
