GENERAL DESCRIPTION

The AD8646 and the AD8647 are the dual, and the AD8648 is

the quad, rail-to-rail, input and output, single-supply amplifiers

featuring low offset voltage, wide signal bandwidth, low input

voltage, and low current noise. The AD8647 also has a low

power shutdown function.

AD8647/AD8648 offer high output drive capability, which is

excellent for audio line drivers and other low impedance

applications. The AD8646 and AD8648 are available for

automotive applications (see the Ordering Guide).

Applications include portable and low powered instrumenta-

tion, audio amplification for portable devices, portable phone

headsets, barcode scanners, and multipole filters. The ability to

swing rail to rail at both the input and output enables designers

to buffer CMOS ADCs, DACs, ASICs, and other wide output

swing devices in single-supply systems.

The combination of 24 MHz bandwidth, low offset, low noise,

and very low input bias current makes these amplifiers useful in

a wide variety of applications. Filters, integrators, photodiode

amplifiers, and high impedance sensors all benefit from the

combination of performance features. AC applications benefit

from the wide bandwidth and low distortion. TheAD8646/
