Part Name(s) : SSM2211P ADI
Analog Devices
Description : Low Distortion 1.5 Watt Audio Power Amplifier View

GENERAL DESCRIPTION
The SSM2211 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 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 operating from batteries, it will continue 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, distortion below 0.2 % THD @ 1 W, and the patented Thermal Coastlineleadframe, superior performance is delivered at higher Power or lower speaker load impedance than competitive units. The advanced mechanical packaging of the SSM2211 gives lower chip temperature, which ensures highly reliable operation and enhanced trouble free life.
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 the Shutdown mode, which reduces quiescent current drain to typically 100 nA.
The SSM2211 is designed to operate over the –20°C to +85°C temperature range. See Figure 49 for information on the Thermal Coastline lead frame. The SSM2211 is available in an SO-8 surface mount package. DIP samples are available; you should request a special quotation on production quantities. An evaluation board is available upon request of your local Analog Device sales office.
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.
