FEATURES:
* Rad-Pak(R) technology-hardened against natural space radiation * Total dose hardness: - >100 krad (Si), depending upon orbit and space mission * Package: * - 14 pin Rad-Pak(R) flat package * Rail-to-Rail input common-mode voltage range (guaranteed over temperature * Rail-to-Rail output swing (within 20 mV of supply rail, 100 k load) * Guaranteed 3V, 5V and 15V performance * Excellent CMRR and PSRR: 82 dB * Ultra low input current: 20 pA * High voltage gain (RL = 500 k): 130 dB * Specified for 2 k and 600 loads
DESCRIPTION:
Maxwell Technologies' 6484 provides a common-mode range that extends to both supply rails. This rail-to-rail performance combined with excellent accuracy, due to a high CMRR< makes it unique among rail-to-rail input amplifiers. It is ideal for systems, such as data acquisition, that require a large input signal range. Maximum dynamic signal range is assured in low voltage and single supply systems by the 6484's rail-to-rail output swing. The device's rail-to-rail output swing is guaranteed for loads down to 600. Guaranteed low voltage characteristics and low power dissipation make the 6484 especially well-suited for battery-operated systems. Maxwell Technologies' patented RAD-PAK(R) 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. In a GEO orbit, RAD-PAK provides greater than 100 krad (Si) radiation dose tolerance. This product is available with screening up toMaxwell Technologies self-defined Class K.

1. Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. 2. Limiting input pin current is only necessary for input voltages that exceed absolute maximum input voltage ratings. 3. Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature can result in exceeding the maximum allowed junction temperature of 150C. Output currents in excess of 30 mA over long term may adversely affect reliability. 4. Do not short circuit output to V+, when V+ is greater than 13V or reliability will be adversely affected. 5. Human body model, 1.5 k in series with 100 pF. All pins rated per method 3015.6 of MIL-STD-883. This is a Class 2 device rating.
