The SSM2250 is intended for use in desktop computers that have basic audio functions. It is also ideal for any audio system that needs to provide both an internal monaural speaker and a stereo line or headphone output. Combined with an AC97 Codec, it provides a PC audio system that meets the PC98/99 requirements. The SSM2250 is compact and requires a minimum of external components.

The SSM2250 features an audio amplifier capable of delivering 1.5 W of low distortion power into a mono 4 Ohm bridged-tied load (BTL) or 2 x 90 mW into stereo 32 Ohm single-ended load (SEL) headphones. Both amplifiers provide rail-to-rail outputs for maximum dynamic range from a single supply. The balanced output provides maximum output from 5 V supply and eliminates the need for a coupling capacitor.

The SSM2250 is able to automatically switch between an internal mono speaker and external headphones.

The SSM2250 is able to run from a single supply, ranging from +2.7 V to +6 V, with an active supply current of 9 mA typical. The ability to shut the amplifiers down, (60 µA shutdown current) makes the SSM2250 an ideal speaker amplifier for battery powered applications.
