GENERAL DESCRIPTION
The SSM2275 and SSM2475 use the Butler Amplifier front
end, which combines both bipolar and FET transistors to offer
the accuracy and low noise performance of bipolar transistors
and the slew rates and sound quality of FETs. This product
family includes dual and quad rail-to-rail output
audio amplifi-
ers that achieve lower production costs than the industry stan-
dard OP275 (the first Butler Amplifier offered by Analog
Devices). This lower cost amplifier also offers operation from a
single 5 V supply, in addition to conventional
±
15 V supplies.
The ac performance meets the needs of the most demanding au-
dio applications, with 8 MHz bandwidth, 12 V/
μ
s slew rate and
extremely low distortion.
The SSM2275 and SSM2475 are ideal for application in high
performance audio amplifiers, recording equipment, synthesiz-
ers, MIDI instruments and computer sound cards. Where cas-
caded stages demand low noise and predictable performance,
SSM2275 and SSM2475 are a cost effective solution. Both are
stable even when driving capacitive loads.
The ability to swing rail-to-rail at the outputs (see Applications sec-
tion) and operate from low supply voltages enables designers to at-
tain high quality audio performance, even in single supply systems.
The SSM2275 and SSM2475 are specified over the extended
industrial (–40
°
C to +85
°
C) temperature range. The SSM2275 is
available in 8-lead plastic DIPs, SOICs, and microSOIC surface-
mount packages. The SSM2475 is available in narrow body
SOICs and thin shrink small outline (TSSOP) surface-mount
packages.
