SSM2375CBZ-REEL

Overview

The SSM2375CBZ-REEL is a mono Class-D audio amplifier from Analog Devices. It delivers 3 W into a 3 Ω load and 1.4 W into an 8 Ω load at a 5.0 V supply, achieving a 100 dB signal-to-noise ratio. The device operates on a single supply voltage ranging from 2.5 V to 5.5 V. It features a filterless design utilizing spread-spectrum Σ-Δ modulation for high efficiency and low electromagnetic interference. The amplifier includes flexible gain adjustment from 0 dB to 12 dB in 3 dB steps, pop-and-click suppression, and short-circuit protection with autorecovery.

Feature Summary

Filterless Class-D architecture using spread-spectrum Σ-Δ modulation to minimize external component count and reduce radiated emissions.
Integrated pop-and-click suppression circuitry to eliminate audible transients during power-up and shutdown sequences.
User-selectable gain control allowing configuration of 0 dB, 3 dB, 6 dB, 9 dB, or 12 dB via a dedicated pin.
Ultralow EMI emissions mode selectable via the EDGE pin to facilitate compliance with FCC Class B standards.

Applications

Mobile phones
MP3 players
Portable electronics

Procurement Notes

Verify the specific ordering suffix (REEL vs REEL7) against current manufacturer documentation to ensure correct packaging format. Confirm RoHS compliance status as indicated by the Z suffix. Check for any recent revision updates that may affect electrical specifications or thermal characteristics before finalizing procurement.

Selection Notes

Select this component for applications requiring high efficiency and minimal board space due to its filterless design. Ensure the load impedance matches the specified output power ratings to maintain performance. Consider the ultralow EMI mode if the application requires strict electromagnetic compatibility testing without external shielding.

Part Context

This part belongs to the SSM2375 series of high-efficiency mono Class-D audio amplifiers. It is designed specifically for mobile phone applications where maximizing battery life and minimizing acoustic noise are critical. The device integrates overcurrent and overtemperature protection to enhance system reliability.
