FEATURES:
- R AD-PAK® radiation-hardened against natural space radiation Package: - 8-pin R AD-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) DESCRIPTION: 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. 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 AD-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 Q1 Q3 QL1 QL2 Q4 Q2 R4 QB6 QB5 Q11 Q12 Q10 QB9 RB3 QB10 RB4 CFF CC2 Q16 Q17 R11 CO Q18 QB3 RB2 Q13 Q14 Q15 R1 R2 QB4 CC1 QB7 QB8 R8 R10 RB1 JB1 QB2 CB1 M QB1 JB2 -IN +IN OUT VCC VEE TP Logic Diagram Flat Pack Leadless Chip Carrier (LCC) OP284A OP284A
