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
2.7V 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 Coastline leadframe, 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.
*. Patent No. 5,519,5761.5 W @ 4 Ω, +25°C ambient, < 1% THD, 5 V supply, 4 layer PCB.Bridge Tied Load

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 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.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the SSM2211 features proprietary ESD protection circuitry, permanent damage may occur on
devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.

TYPICAL APPLICATION

Figure 39.A Typical Configuration
Figure 39 shows how the SSM2211 would be connected in a
typical application. The SSM2211 can be configured for gain
much like a standard op amp. The gain from the audio input to
the speaker is:
The 3 2 factor comes from the fact that Pin 8 is opposite polar-
ity from Pin 5, providing twice the voltage swing to the speaker
from the bridged output configuration.
CS is a supply bypass capacitor to provide power supply filter-
ing. Pin 2 is connected to Pin 3 to provide an offset voltage for
single supply use, with CB providing a low AC impedance to
ground to help power supply rejection. Because Pin 4 is a virtual
AC ground, the input impedance is equal to RI. CC is the input
coupling capacitor which also creates a high-pass filter with a
corner frequency of:
Because the SSM2211 has an excellent phase margin, a feed-
back capacitor in parallel with RF to band-limit the amplifier is
not required, as it is in some competitor’s products.
Bridged Output vs. Single Ended Output Configurations

The power delivered to a load with a sinusoidal signal can be ex-
pressed in terms of the signal’s peak voltage and the resistance
of the load:
By driving a load from a bridged output configuration, the volt-
age swing across the load doubles. An advantage in using a
bridged output configuration becomes apparent from Equation
3 as doubling the peak voltage results in four times the power
delivered to the load. In a typical application operating from aV supply, the maximum power that can be delivered by the
SSM2211 PRODUCT OVERVIEW

The SSM2211 is a low distortion speaker amplifier that can run
from a 1.7V to 5.5V supply. It consists of a rail-to-rail input
and a differential output that can be driven within 400mV of
either supply rail while supplying a sustained output current of
350mA. The SSM2211 is unity-gain stable, requiring no exter-
nal compensation capacitors, and can be configured for gains of
up to 40dB. Figure 38 shows the simplified schematic.

Figure 38.Simplified Schematic
Pin 4 and Pin 3 are the inverting and noninverting terminals to A1.
An offset voltage is provided at Pin 2, which should be connected
to Pin 3 for use in single supply applications. The output of A1
appears at Pin 5. A second op amp, A2, is configured with a fixed
gain of AV=–1 and produces an inverted replica of Pin 5 at Pin8.
The SSM2211 outputs at Pins 5 and 8 produce a bridged configu-
ration output to which a speaker can be connected. This bridge
configuration offers the advantage of a more efficient power trans-
fer from the input to the speaker. Because both outputs are sym-
metric, the dc bias at Pins 5 and 8 are exactly equal, resulting in
zero dc differential voltage across the outputs. This eliminates the
need for a coupling capacitor at the output.
The SSM2211 can achieve 1W continuous output into 8Ω, even
at ambient temperatures up to +85°C. This is due to a propri-
etary SOIC package from Analog Devices that makes use of an
internal structure called a Thermal Coastline. The Thermal
Coastline provides a more efficient heat dissipation from the die
than in standard SOIC packages. This increase in heat dissipation
allows the device to operate in higher ambient temperatures or at
higher continuous output currents without overheating the die.
For a standard SOIC package, typical junction to ambient tem-
perature thermal resistance (uJA) is +158°C/W. In a Thermal
Coastline SOIC package, uJA is +98°C/W. Simply put, a die in a
Thermal Coastline package will not get as hot as a die in a stan-
dard SOIC package at the same current output.
Because of the large amounts of power dissipated in a speaker
amplifier, competitor’s parts operating from a 5V supply can
only drive 1W into 8Ω in ambient temperatures less than
