SSM2475

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.

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.
