SSM2302 - Filterless High Efficiency Class-D Stereo Audio Amplifier

Description

The SSM2302 is a fully integrated, high efficiency, Class-D stereo audio amplifier.

It is designed to maximize performance for mobile phone applications.

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

Features

  • Filterless Class-D amplifier with built-in output stage 1.4 W into 8 Ω at 5.0 V supply with less than 1% THD 85% efficiency at 5.0 V, 1.4 W into 8 Ω speaker Better than 98 dB SNR (signal-to-noise ratio) Single-supply operation from 2.5 V to 5.0 V 20 nA ultralow shutdown current Short-circuit and thermal protection Available in 16-lead, 3 mm × 3 mm LFCSP Pop-and-click suppression Built-in resistors reduce board component count Fixed and user-adjustable gain configurations 5.0 V supply and has a.
