GENERAL DESCRIPTION

The SSM2211³is 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.

shutdown mode, which typically reduces quiescent current

drain to 100 nA.

The SSM2211 is designed to operate over the –40°C to +85°C

temperature range. The SSM2211 is available in 8-lead SOIC

(narrow body) and LFCSP (lead frame chip scale) surface-

mount packages. The advanced mechanical packaging of the

LFCSP models ensures lower chip temperature and enhanced

performance relative to standard packaging options.

Applications include personal portable computers, hands-free

telephones and transceivers, talking toys, intercom systems, and

other low voltage audio systems requiring 1 W output power.

The low differential dc output voltage results in negligible

losses in the speaker winding and makes high value dc blocking

capacitors unnecessary. Battery life is extended by using

²Bridge-tied load.
