Overview
Filterless, High Efficiency, Mono 3 W Class-D Audio Amplifier SSM2315 FEATURES Filterless Class-D amplifier with Σ-Δ modulation No sync necessary when using multiple Class-D amplifiers from Analog Devices, Inc.
3 W into 3 Ω load and 1.
4 W into 8 Ω load at 5.
0 V supply with <1% total harmonic distortion (THD + N) 93% efficiency at 5.
0 V, 1.
4 W into 8 Ω speaker >103 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 9-ball, 1.
5 mm × 1.
5 mm WLCSP Pop-and-click suppression Built-in resistors reduce board component count Default fixed 6 dB or user adjustable gain setting The SSM2315 features a high efficiency, low noise modulation scheme that requires no external LC output filters.
The modulation continues to provide high efficiency even at low output power.
It operates with 93% efficiency at 1.
