SSM2304 - 2 W Filterless Class-D Stereo Audio Amplifier

Description

The SSM2304 is a fully integrated, high efficiency, Class-D stereo audio amplifier.

It is designed to maximize performance for portable applications.

The application circuit requires a minimum of external components and operates from a single 2.2 V to 5.0 V supply.

Features

  • Filterless Class-D amplifier with built-in output stage 2 W into 4 Ω and 1.2 W into 8 Ω at 5.0 V supply with less than 10% THD 85% efficiency at 5.0 V, 2W into 4 Ω speaker Better than 95dB SNR (signal-to-noise ratio) Available in 16-lead 3 mm × 3 mm LFCSP Single-supply operation from 2.2 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 18dB gain and user-adjustable 2 W Filterle.
