Maxwell Technologies
’ OP284A is a dual single-supply, 4
MHz bandwidth amplifier featuring rail-to-rail inputs and out-
puts. Using
Maxwell Technologies
’ radiation-hardened R
AD
-
P
AK
® technology, it is guaranteed 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 OP284A useful
in a wide variety of applications, including filters and instru-
mentation. Other applications for this amplifier include porta-
ble 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

® 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. This product is available with screening up to Class
S.
