Leadless Chip Carrier (LCC)
FEATURES:
DESCRIPTION:
• RAD-PAK® radiation-hardened against natural space radia-
tion
• Total dose hardness:
- > 100 krad (Si), depending upon space mission
• Package:
Maxwell Technologies’ OP284 is a dual single-supply, 4
MHz bandwidth amplifier featuring rail-to-rail inputs and out-
puts and a greater than 100 krad (Si) total dose tolerance,
depending upon space mission. Using Maxwell Technolo-
gies’ radiation-hardened RAD-PAK® technology, it is guaran-
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.
- 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
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 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.
• High Slew Rate: 4.0 V/ms
½
• Low Noise: 3.9 nV/(Hz)
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 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. In a GEO orbit, RAD-PAK® provides greater than 100
krad (Si) radiation dose tolerance. This product is available
with screening up to Class S.

1. Guaranteed by design.
2. Power consumption is based upon quiescent supply current maximum test limit. No load on outputs.
3. Full power bandwidth is based on slew rate measurement using FBBW = slew rate/(2PVPEAK).
