SSM2211 - Low Distortion 1.5W Audio Power Amplifier

General Description

The SSM22111 is a high performance audio amplifier that delivers 1 W rms of low distortion audio power into a bridgeconnected 8 Ω speaker load (or 1.5 W rms into a 4 Ω load).

The SSM2211 operates over a wide temperature range and is specified for single-supply voltages between 2.7 V and 5.5 V.

Key Features

  • 1.5 W output with THD + N < 1% Differential bridge-tied load output Single-supply operation: 2.7 V to 5.5 V Functions down to 1.75 V Wide bandwidth: 4 MHz Highly stable phase margin: >80° Low distortion: 0.2% THD + N at 1 W output Excellent power supply rejection.
