SSM2211
SSM2211 is a high-performance audio amplifier that can deliver low distortion audio power of 1W rms to a bridged 8Ω speaker load (or 1.5W rms load).
SSM2211 can operate within a wide temperature range and is suitable for single power supply voltages between 2.7V and 5.5V.
SSM2211 is designed to operate within a temperature range of -40°C to+85°C. SSM2211 provides 8-pin SOIC (narrow body) and LFCSP (lead frame chip level) surface mount packaging

SSM2211 General description:
The SSM2211 is a high performance audio amplifier that delivers 1W rms of low distortion audio power into a bridge-connected 8Ω speaker load (or 1.5W rms into a 4Ω load).
The SSM2211 operates over a wide temperature range and is specified for single-supply voltages between 2.7V and 5.5V. When operating from batteries, it continues to operate down to 1.75V. 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% total harmonic distortion plus noise (THD+N) at 1W, superior performance is delivered at higher power or lower speaker load impedance than competitive units. Furthermore, when the ambient temperature is at 25°C, THD+N<1%, and VS=5V on a 4-layer printed circuit board (PCB), the SSM2211 delivers a 1.5W output.
The low differential dc output voltage results in negligible losses in the speaker winding and makes high value dc blocking capacitors unnecessary. The battery life is extended by using shutdown mode, which typically reduces quiescent current drain to 100nA.
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 1W output power.
