The SSM2211 is a high performance audio amplifier that delivers 1 W RMS of low distortion audio power into a bridge-connected 8 speaker load, (or 1.5 W RMS into 4 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. This makes the SSM2211 the best choice for unregulated applications such as toys and games. Featuring a 4 MHz bandwidth, distortion below 0.2 % THD @ 1 W, and the patented Thermal Coastline leadframe, superior performance is delivered at higher power or lower speaker load impedance than competitive units. The advanced mechanical packaging of the SSM2211 gives lower chip temperature, which ensures highly reliable operation and enhanced trouble free life.
