SSM2317 - Filterless High Efficiency Mono 3 W Class-D Audio Amplifier

Description

The SSM2317 is a fully integrated, high efficiency, Class-D audio amplifier.

It is designed to maximize performance for mobile phone applications.

Features

  • Filterless Class-D amplifier with Σ-Δ modulation Automatic level control (ALC) improves dynamic range and prevents clipping 3 W into 3 Ω load and 1.4 W into 8 Ω load at 5.0 V supply with 93 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 ×.
