GENERAL DESCRIPTION
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 PC99
requirements. The SSM2250 is compact and requires a mini-
mum of external components.
The SSM2250 features an audio amplifier capable of delivering
1.5 W of low distortion power into a mono 4 Ω bridge-tied load
(BTL) or 2 × 90 mW into stereo 32 Ω single-ended load (SE)
headphones. Both amplifiers provide rail-to-rail outputs for
maximum dynamic range from a single supply. The balanced
output provides maximum output from a 5 V supply and
eliminates the need for a coupling capacitor.
The SSM2250 can automatically switch between an internal
mono speaker and external headphones. The device can 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 down the
amplifiers (60 μA shutdown current) makes the SSM2250 an
ideal speaker amplifier for battery-powered applications.
The SSM2250 is specified over the industrial (−40°C to +85°C)
temperature range. It is available in a 14-lead TSSOP and a
10-lead, surface mount MSOP package.
