DESCRIPTION:
Maxwell Technologies’ 6484 provides a common-mode range
that extends to both supply rails. This rail-to-rail performance
combined with excellent accuracy, due to a high CMRR<
makes it unique among rail-to-rail input amplifiers. It is ideal
for systems, such as data acquisition, that require a large
input signal range.
Maximum dynamic signal range is assured in low voltage and
single supply systems by the 6484’s rail-to-rail output swing.
The device’s rail-to-rail output swing is guaranteed for loads
down to 600Ω. Guaranteed low voltage characteristics and
low power dissipation make the 6484 especially well-suited for
battery-operated systems.
Maxwell Technologies' patented RAD-PAK® packaging technol-
ogy incorporates radiation shielding in the microcircuit pack-
age. It eliminates the need for box shielding while providing
the required radiation shielding for a lifetime in orbit or space
mission. In a GEO orbit, RAD-PAK provides greater than 100
krad (Si) radiation dose tolerance. This product is available
with screening up toMaxwell Technologies self-defined Class
