SSM2356CBZ-RL

Overview

The SSM2356CBZ-RL is a stereo Class-D audio amplifier from Analog Devices, operating on a single supply voltage ranging from 2.5 V to 5.5 V. It delivers up to 2 W per channel into a 4 Ω load and 1.4 W into an 8 Ω load at 5.0 V. The device utilizes Σ-Δ modulation for filterless operation, achieving a signal-to-noise ratio of 103 dB and a total harmonic distortion plus noise of 0.004%. It features a shutdown current of 20 nA, user-selectable gain settings of 6 dB or 18 dB, and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Filterless stereo Class-D architecture using Sigma-Delta modulation eliminates the need for output filters.
• Integrated pop-and-click suppression minimizes audible transients during power-up and power-down cycles.
• User-selectable gain configuration allows switching between 6 dB and 18 dB without changing input impedance.
• Ultralow EMI emission mode reduces radiated emissions, particularly above 100 MHz.

Applications

• Mobile phones
• MP3 players
• Portable gaming devices
