Manufacturer: Analog Devices

Overview: Data Sheet.

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.

When operating from batteries, it continues to operate down to 1.75 V.

Key Features
