SSM2306 - Class-D Stereo Audio Amplifier

General Description

The SSM2306 is a fully integrated, high efficiency, Class-D stereo audio amplifier designed to maximize performance for portable applications.

The application circuit requires minimum external components and operates from a single 2.5 V to 5.0 V supply.

Key Features

  • Filterless Class-D amplifier with built-in output stage 2 W into 4 Ω and 1.4 W into 8 Ω at 5.0 V supply Ultralow idle current with load resistance >87% efficiency at 5.0 V, 1.4 W into 8 Ω speaker Better than 96 dB SNR (signal-to-noise ratio) Available in 16-lead, 3 mm × 3 mm LFCSP Single-supply operation from 2.5 V to 5.0 V 20 nA ultralow shutdown current Short-circuit and thermal protection Pop-and-click suppression Built-in resistors reduce board component count Default fixed 18 dB gain and us.
