FEATURES:
DESCRIPTION:
• RAD-PAK® radiation-hardened against natural space
• radiation
• Package:
- 8-pin RAD-PAK® flat pack
- 16-pin RAD-PAK® Leadless Chip Carrier (LCC) pack
• Single-Supply Operation
• Wide Bandwidth: 4 MHz
• Low Offset Voltage: 65uV
• Unity-Gain Stable
• High Slew Rate: 4.0 V/us
• Low Noise: 3.9 nV/(Hz)½
Maxwell Technologies’ OP284A is a dual single-supply, 4
MHz bandwidth amplifier featuring rail-to-rail inputs and outputs. Using Maxwell Technologies’ radiation-hardened RADPAK® 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 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 RAD-PAK® packaging technology 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. This product is available with screening up to Class
S.
