The SSM2211 is a high performance audio amplifier that delivers 1W rms of low distortion audio power into a bridge-connected 8ohm speaker load (or 1.5W rms into a 4ohm load). The SSM2211 operates over a wide temperature range and is specified for single-supply voltages between 2.7V and 5.5V. When operating from batteries, it continues to operate down to 1.75V. This makes the SSM2211 the best choice for unregulated applications, such as toys and games.
