Leadless Chip
Carrier (LCC)
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
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 RAD-
PAK® 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.
•
• 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 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.
• High Slew Rate: 4.0 V/us
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. This product is available with screening up to Class
S.
