Overview
Filterless High Efficiency Mono 2.
8 W Class-D Audio Amplifier SSM2305 FEATURES Filterless Class-D amplifier with Σ-Δ modulation No sync necessary when using multiple Class-D amplifiers from Analog Devices, Inc.
2.
8 W into 4 Ω load and 1.
6 W into 8 Ω load at 5.
0 V supply with <10% total harmonic distortion (THD) 89% efficiency at 5.
0 V, 1.
3 W into 8 Ω speaker >98 dB signal-to-noise ratio (SNR) Single-supply operation from 2.
5 V to 5.
5 V 20 nA ultralow shutdown current Short-circuit and thermal protection Available in 8-lead, 3 mm × 3 mm LFCSP and MSOP Pop-and-click suppression Built-in resistors reduce board component count Fixed and user-adjustable gain configurations The SSM2305 features a high efficiency, low noise modulation scheme that does not require external LC output filters.
The modulation provides high efficiency even at low output power.
The SSM2305 operates with 90% efficiency at 1.
