FEATURES:
• Rad-Pak® technology-hardened against natural space
radiation
• Total dose hardness:
- >100 krad (Si), depending upon orbit and space mission
• Package:
• - 14 pin Rad-Pak® flat package
• Rail-to-Rail input common-mode voltage range (guaranteed over temperature
• Rail-to-Rail output swing (within 20 mV of supply rail, 100
k
Ω load)
• Guaranteed 3V, 5V and 15V performance
• Excellent CMRR and PSRR: 82 dB
• Ultra low input current: 20 pA
• High voltage gain (RL = 500 k
Ω): 130 dB
• Specified for 2 k
Ω and 600 Ω loads
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 600
Ω. Guaranteed low voltage characteristics and
low power dissipation make the 6484 especially well-suited for
battery-operated systems.
Maxwell Technologies' patented R
AD-PAK® packaging technol-
ogy incorporates radiation shielding in the microcircuit package. 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, R
AD-PAK provides greater than 100
krad (Si) radiation dose tolerance. This product is available
with screening up to Class S.

can result in exceeding the maximum allowed junction temperature of 150°C. Output currents in excess of ±30 mA over long
term may adversely affect reliability.
