Engineering reference data for OP42ARC/883C — comparison, design guidance, and compliance information.

Selection Guide

Choose OP42ARC/883C when you need a military-grade, high-speed JFET op amp with a wide temperature range and ceramic package. It is ideal for aerospace, defense, and high-reliability applications. For commercial applications, the OP42AZ or OP42GP offer the same electrical performance at lower cost. If you need a lower slew rate but lower power, consider the AD711. The LF400 is a direct replacement per the datasheet, but verify pinout and package compatibility. For designs requiring a standard 8-pin DIP, the OP42AZ is a drop-in replacement, but note the package difference from the CLCC-20.

  • Higher slew rate than AD711 (vs AD711)
  • Lower input bias current than LF400 (vs LF400)

Design Notes

The OP42ARC/883C operates from ±15 V supplies. Use 0.1 µF ceramic capacitors close to the V+ and V- pins to decouple high-frequency noise. Additionally, a 10 µF tantalum capacitor on each supply rail can help maintain stability during transient load changes. Ensure the supply voltages are within the absolute maximum ratings to prevent damage.

For optimal performance, place the OP42ARC/883C away from high-frequency digital circuits to minimize noise coupling. Use a ground plane to provide a low-impedance return path. Keep input traces short and shielded if necessary. The CLCC-20 package has an exposed pad; solder it to a thermal pad on the PCB to improve heat dissipation.

Avoid driving capacitive loads directly without isolation, as this can cause oscillation. Use a series resistor (e.g., 50 Ω) at the output if driving cables or long traces. Also, ensure the input common-mode voltage does not exceed the specified range to prevent phase reversal. The OP42 is internally compensated for unity gain, but external compensation may be needed for non-inverting gains less than 1.
