I/O Op Amp

02.14.02 R ev 2

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.
