DESCRIPTION:

Maxwell Technologies’ OP284 is a dual single-supply, 4

MHz bandwidth amplifier featuring rail-to-rail inputs and out­puts and a greater than 100 krad (Si) total dose tolerance,
depending upon space mission. Using

’ radiation-hardened RAD-PAK® technology, it is guaran-

gies

teed to operate from +3 to +36 (or ±1.5 to ±18) volts and will
function with a single supply as low as +1.5 volts.

This amplifier is superb for single supply applications requiring
both ac and precision dc performance. The combination of
bandwidth, low noise and precision makes the OP284 useful
in a wide variety of applications, including filters and instru­mentation. Other applications for this amplifier include porta­ble telecom equipment, power supply control and protection,
and as an amplifier or buffer for transducers with wide output
ranges.

The ability to swing rail-to-rail at both the input and output
enables designers to build multi-stage filters in single-supply
systems and to maintain high signal-to-noise ratios.

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.
