GENERAL DESCRIPTION

The AD8648 is a quad, rail-to-rail, input and output, single-

supply amplifier featuring low offset voltage, wide signal

bandwidth, and low input voltage and current noise.

Applications for the part include portable and low powered

instrumentation, audio amplification for portable devices,

portable phone headsets, bar code 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. The AD8648

family offers high output drive capability, which is excellent for

audio line drivers and other low impedance applications.
