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/µs slew rate and  
extremely low distortion.

SSM2275  
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.
