SSM2211 Datasheet PDF

●GENERAL DESCRIPTION

●The SSM22113 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 oper ating from batteries, it continues 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 and distortion below 0.2% THD + N @ 1 W, superior performance is delivered at higher power or lower speaker load impedance than competitive units.
