GENERAL D ESCRIP TIO N

The low differential dc output voltage results in negligible losses

in the speaker winding, and makes high value dc blocking capaci-

tors unnecessary. Battery life is extended by using the Shutdown

mode, which reduces quiescent current drain to typically 100 nA.

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 de-

livered at higher power or lower speaker load impedance than com-

petitive units. The advanced mechanical packaging of the SSM2211

gives lower chip temperature, which ensures highly reliable operation

and enhanced trouble free life.

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 sur-

face 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.
