The SSM2211 is a high-performance audio amplifier that delivers 1 W RMS of low-distortion audio power into a bridge-connected 8 Ω speaker load, (or 1.5 W RMS into a 4 Ω load). It 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 will continue to operate down to 1.75 V, making the SSM2211 the best choice for unregulated portable computers, personal wireless communicators, hands-free telephones, speakerphones, intercoms, musical toys and speaking games.
