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.
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.
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.
