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.
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/

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.
